You should use every variant of the first two KOTOR-s endings to take the story to the "edge".
Like: Episode1 ending Good, Episode2 ending Good: There is a new jedi Council with members of the 2nd KOTOR (like Disciple), Revan is good, Taris had been saved, there are some survivors on it in an underground city(KOTOR1 mission), maybe Bindo is a member from the Jedi Council too?
Episode1 ending Good, Episode2 ending Evil: Revan is good, but there is no new Jedi Council, There is a new Sith Lord (the character from KOTOR2), some characters fight the Evil in the Galaxy (from Episode1), and so on...
Episode1 ending Evil, Episode2 ending Evil: The Galaxy is near the destruction, no JC, no Jedi at all(?)...
I realize, this would make minimum 4 timelines in one game, and VERY MUCH work, but this will bring the trilogy a perfect ending, and "fame" for OBSIDIAN, and I think this would be worth of it. :cool:
