As an amateur tinkerer, I whipped up my own version of D20 Traveller as a lark back at about Christmas time. I thought the two things that had to be changed about d20 to make it feel more like Traveller was the obscene piling up of hit points and allowing for prior-service to be included in character generation.
What I did was to change hit points to a base equal to Constitution, and added only 1 hitpoint per level for most classes except for Army and Marines who got 2 hit points on odd numbered levels and 1 on even numbered levels. I think people like getting more hit points when they go up levels (one of the appeals of a level based system is the striving after the level-rewards), but a die per level is just gross.
I translated the CT prior expereince tables to d20 terms and made it so that 1 term got you 1 level, with a chance each term to dice for a bonus level (like Special Duty in MT).
(Of course I added Social Status ads a 7th ability score too).
