The only races i can see working would be Near-humans due to a few things like romancing has to be somewhat believable , how easily they can make it so gear looks proper on them that kind of stuff. With that the ones i'd like to see that would also work are:
Nautolan
Togruta
Devaronian
Duros
Chagrian ( Sergeant Rusk)
Weequay Could possibly work.
Sarkhai if you want a reskinned human ( Nadia Grell)
Houk but that might be pushing it.
just a small list , seeing as theres MANY races and near-human races they could use , just pointing out a few that are well known / somewhat known.
