Changes I'd make to Ady's "Revisited" (not counting the "Purist" edition, which I know contains some of the changes I'd like to make, but removes some of the changes I liked about ANH:R):

1. Remove the torture droid's mini-lightsaber-needle-thingie. If there's one change to be made to ANH:R, that's it.

2. Return Obi-Wan's death to normal speed, with the original music (I'm indifferent on the duel music - it's a little out of place, but not too bad).

3. Remove the music in the Death Star "briefing" room. The only bit of truly unnecessary added music.

That's it. Otherwise, it's THE perfect version of ANH.

Oh, almost forgot, one more change:

Re-do the whole thing at 4K (or even 6K) resolution and print it back to 35mm film for theatrical distribution.
