You're right. Though it would be pretty easy to change the Name and to remove the 'Bastila's Mother' quest you'd have to change nearly every to every conversation ingame to not use the Name Bastila and to use the name Sunrider. Conclusion: You have to record new Voices for every
character and so on. That'll be a LOT to work on...
