Characters that'd be great to see introduced

I think a Revan that is neutral or counts as both light side and dark side would be cool, have the mask and a purple saber, maybe attainable through an event like Yoda and Emporer Palpatine, he could have abilities that boost both jedi and sith and have synergies with HK-47 and Bastilla Shan... oh wait she would need to be in the game first

Bastilla Shan as a jedi support with double bladed yellow saber and battle meditation that grants the whole squad boosts of some sort.

I would like to see jedi versions of Luke (either the "rebel" that serves as a boss on I forget which level but has the outfit from Bespin with the blue saber and/or the black outfit with the green saber)

I also second the addition of droideka and HK-50/51, Mara jade, Kyle katarn, grand inquisitor, Ezra Bridger, Canaan jarus, and jango fett.
