IMU (systemless sci-fi rather then traveller) people were purpose built. It helped that interstellar travel made you infertile in as little as one trip. If you have to start from a vat, you may as well tinker.
In that universe I suppose you could consider nearly everyone supermen to some degree.
Common funtional adaptions:
Vacuum capable orifi (nostrils, urinary tract, anus, mouth). Often mixed with an unusually flat and thick bone structure around the eyes, this is to simplify surgically embedding eye covers.
Oxygen storage organ. Stores excess oxygen. This is useful for short term exposure to vacuum/low oxygen environments. The militarised version allows dumping excess oxygen into the blood stream at will.
Concious metabolic manipulation. This allows self directed hibernation.
... along with the expected modifications which are basically just selection from the outlying population. ie. When you have a choice use the best adapted muscle, digestive, connective, cognitive and skeletal systems you can locate.
Anyway, those were just my ideas.
