Ya'll're welcome: I just hope we can come up with something that's useable. Here's the numbers I got for turning 8-ship squadrons of the Supplement #9 ships into FFW counters. I assumed that ships were not prepared for Bombardment, but did have sufficient escorts and cargo space.

Here's a suggested revision of the methods for calculating FFW ratings for HG ships. The changes are in bold face.
*************************************
Rating HG ships and squadrons for FFW
Definitions:
Main ship - A ship of the same type as the type of squadron; battleships and battleriders are the main ships of BatRons, cruisers are the main ships of CruRons, assault ships are the main ships of AssaultRons, tankers are the main ships of TankRons, and scouts are the main ships of ScoutRons.
Capital ship - A ship carrying a spinal mount, intended for the line of battle. Capital ships are usually armored and of high acceleration and Agility, carrying the best computers available.
Escort - A ship without a spinal mount, but intended for combat.
Fighter - A combat ship of less than 100 tons.

The same holds true for fighters based on ships in battleship squadrons; those fighters are assumed to be needed for screening the capital ships and therefore not to be expended.
Note: To find the number of "effective missile batteries" on a ship with turret missile racks, count the total number of missile racks (not turrets, not batteries, actual missile racks) on the ship and divide by 30.

Practice. Now that's a good idea.
Let's see... I need to know:
*1. All spinal mount types
2. Average capital ship computer rating
3. Escort tonnage to Main-ship tonnage %
4. Effective missile battery count
5. Fighter count
**6. Tradeoff of attack value for bombardment
7. Cargo hold tonnage to Capital-ship tonnage %
8. # of 30kton+ capital ship hulls
9. # of remaining capital ship hulls
10. Average capital ship agility
11. Average capital ship meson screen rating
12. Average capital ship damper rating
13. Average capital ship armor rating
* Is there a way to calculate the "Average" spinal weapon type?
** Suggestion: set a value for "bombardment preparation". If I sacrifice one point of attack value, how many bombardment points do I get? 2? 3? 4?

As a rough rule of thumb, for meson guns they tend to appear at each TL as light, medium and heavy.
Very light battle riders mount light meson guns, as do light cruisers.
Light battle riders mount medium meson guns, as do medium/heavy cruisers.
Medium battle riders mount heavy meson guns, as do battleships.
What counts as very light, light etc. for ships varies with TL as well
The best way is to break out High Guard and build them

I was intending to create a system to translate HG designs into FFW-like counters, so HG is the way to make the ships.
As for the +1 for preparing for Bombardment, I would say that you'd have to empty non-missile weapons bays equal to half that ship's number of missile batteries. This only works with weapon bays, you can't "remove" turret weapons. There are actually few existing ship designs with enough non-missile weapons bays to gain this advantage.
And a ship/squadron that prepares for Bombardment in this way does not lose any Attack value at all, since that is based solely on spinal mounts.

Re: Bombardment: Okay. Thank you.
As an intermediate level between squadrons and single ships, I'd been thinking about how to rate 'task forces': elements of a squadron consisting of a single main ship and its auxiliaries. I tentatively decided that there are two ways to do it:
Bottom-up: if the actual ship type is known, then calculate its values as usual, multiplying ATT and DEF by 8 [sort of arbitrary number]. The combat chart imposes penalties and bonuses based on the relative size difference between attacker and defender. Very high level.
Top-down: if the actual ship types are not known [i.e. we're just given a squadron], break it into N equal task forces, where N is the ATT value. Each task force inherits the ATT and DEF from the squadron stats, but the Bombardment value is not propagated -- it is distributed among the units as the player wishes.
I've also developed combat rules that work between squadron units, task force units, and single ship units. It occurs to me that I may have re-invented the wheel, though...

Did anyone ever take the methods outlined here and try to infer what capital ships were associated with different FFW counters by reverse-engineering the HG stats? For example, this unit was probably a Plankwell, etc.?
I'd be curious to try this with Invasion: Earth.
(Although 11 years old, there's some GREAT work in this thread!)

OK, I am interesting in trying this out for some hypothetical Solomani Rim battles. T20 has two very useful books detailing the period ships of the Imperium (Fighting Ships) and the Confederation (Fighting Ships of the Solomani Confederation), and since T20 ship design is so close to HG it seems like a good test case.
FSotSC details several different FleetRons that have very mixed composition—at most, four main ships of the same class and then up to six more destroyers or cruisers, plus unspecified support ships. While this is probably more realistic, for this exercise I will use the simplifying assumption that each squadron consists of 8 ships of the same type plus unspecified support ships. I will also assume these escorts constitute 10% of the tonnage of the main ships.
So let's begin with the Solomani Prometheus-class fast dreadnought. This is a TL 14, J-4 250,000 ship with class S meson spinal.
So this spinal has a value of 0.95 x 8 = 7.6, rounded to 8 for total Attack Rating.
The Prometheus is size S, so the formula for Bombardment is (# effective missile batteries/400), rounded down, + (# fighters in the squadron/1000), rounded down. There are no missile batteries, and only 30 fighter per ship, so the Bombardment Rating is 0.
The base value for the Defense Rating is 1 for every capital ship hull of 30ktons or larger, so 8. The following modifiers apply:
The FFW squadron rating for the Prometheus-class, then, is 8-0-4. This seems to be in the ballpark compared to the Oz's calculations. The TL 15 rating of the Atlantic, for example, is 6-1-7.
Pretty nifty!

OK, let's try a Solomani Zeus-class battlecruiser: a TL 13, 150kdt ship with a Class P meson spinal.
The Attack Rating is 8 x 0.8 = 6.4, rounded up to 7.
There are no fighters, but Zeus does have "22 Missile Magazines." Not sure if this counts as an "effective missile battery," but even so 22 x 8/400 = .44, rounded to 0 for Bombardment Rating.
For Defense Rating, 8 x 1 point for every capital ship hull of 30ktons or larger = 8. Modified by the following:
So the FFW squadron rating for the Zeus-class is 7-0-5.

Better still the numbers look like they are in the right ballpark.

Here's my initial pass at working up squadrons of the Rim War. I finally found a use for Fighting Ships of the Shattered Imperium: using the "historic designs" to fill in likely gaps. At this level of granularity, the design problems in that book don't matter. For all squadrons I assumed 8 capital ships of the main class unless otherwise noted.

To contrast this, here are the counters for Invasion: Earth:
So this doesn't actually line up particularly closely with my conversions, but the divergences seem fairly consistent, which mean they can probably be adjusted easily enough. The upper end of my Attack Ratings is higher than anything in Invasion Earth; the upper end of my Defense Ratings is lower than in Invasion Earth. Bombardment factors seem to be higher in IE, but those squadrons probably all benefit from the +1 bonus to being prepared for bombardment action, which would bridge the gap for that parameter. Need to think about this a little more.
