By the way, I was thinking reading you in the 77-93 mix comparison thread and just remembered your feedback about my work. I thought: what about the idea to use the SW soundtrack anthology? Ok, I know you can't get rid of the film soundtrack to keep only the SFX's but the SW anthology presents the film mix version of the music. With a bunch of reediting to fit the film edit and with overdubbing you would make a masterpiece... I guess.
I don't know so much about film editing but considering how I managed my last rendition for the Empire score, with this "layering" technic I developped for it (when it looked impossible to me at first), that's exactly how I would work and present a new version of these films: kind of concerto movies with a blowing soundtrack ! ;)
It would just take you a little more time. :)
