Perhaps I missed it, or maybe not, but I think Appearance items would be great. add a new tab under the character sheet, character/ship/companion/APPEARANCE where like your equipment slots, you could equip items and gear only for appearance sake. even though you may have on Heavy Armor and a Rail Gun, you could look like you're in light armor with a rifle. allowing for more variety in character appearance, as well as just coming up with a look you personally like, with out sacrificing the gear you need to have equipped, and of course having unify option for the /APPEARANCE/ gear.
