Hm. I was going to try and figure out a way to alter 2 or 3 of them so one of them turns into a Republic armor set for the player and the others become disguises for Carth, Bastila, Juhani, and Jolee since them walking around in their distinctive outfits on Taris and Korriban is a little... out of place.
EDIT: But I still want the initial clothing to remain vanilla. I'm just not sure how to make it all happen. I imagine it requires modifying the appearance.2da file.
