Man I'm working on it it just costs a crap load to do! And take time to unlock them! just found I need to level a 2nd Sith Warrior to get a light side Jaesa Willsaam... Doh! When I finish the girls all do all the others too.
I've got a LightSide Sith Warrior and enough money to do such a thing.
I *always* get customizations. If you need some help, give a holler.
