I'm going to pop in the DVD bonus disc, and check out what scenes could be re-inserted into an edit, one that comes to mind is the ROTJ throne room saber duel with the correct color sabers, one segment that stands out is when Luke and Vader clash sabers in front of the Emperor's face, on the bonus disc the sabers have white cores...if the quality is comparable, it would be alot easier to insert the scenes, instead of trying to color correct them or draw them in by hand.

Also I like the segment on the bonus disc where they show the Original crawl without "Episode IV or A New Hope attached to it" I remember hearing that someone had actually restored that original crawl to an edit...It would be a nice bonus feature or easter egg.
