I saw what you did with Battle of the heroes cutter, and let me say there's still something knightish in the first four notes of the main melody, perhaps the so wanted Jedi Knights motiv could be extracted or based in those first four notes?

I still think that something joyful could came out of Anakin's dark deeds; and I still encourage you to try it; but I have to say the new clip of Anakin and Obiwan, with your new music fits very, very well.

Another suggestion:

Please use (or work on it) the music you can hear at 6:08 of this link http://www.youtube.com/watch?v=yGMKCrUFuMU . It's a tense section, that I think wasn't used in the movie.

Cheers
