Ember

Maybe, it'd be intresting, to say the very least. It'd be tough to pull off; Zaalbar, for instance, wasn't done very well, in my honest opinion, and therefore I only ever used him two or three times; this is including all the times I played through the game. Not really because he was a bad in terms of usefullness within the games battles and stuff, but rather because he wasn't really intresting as a character, even when you had his whole sidequest thingamajiger on Kashyyk. In my opinion anyways. Rakatan's are awesome though, and I wouldn't mind seeing them again in KOTOR 2.
