In ROTJ I’ll maintain:
-the removal of Leia/Chewie’s arrival to Jabba’s Palace,
-Palpatine arrival to the Death Star as the opening,
-other saga movies’ soundtrack added,
-Vader being less doubtful about the Dark Side (but less edited than the original… for example I’ll keep Palpatine asking to Vader if his feelings are clear). The fact that Luke believes Vader can be saved, and Palpatine’s worries, are enough for the audience. But around this point I’m not 100% sure. I could keep this as the original movie, if I’m really the only one who doesn’t like Vader being doubtful.

Plus:
-Jabba’s palace exterior will be taken from The Mandalorian (if it looks ok)
-Jabba’s palace interior music the first time we enter will be changed, if possible (I hate the original)
-Endor’s planet view will be blue-ish again, or at least not that hard green I added in the edit

EDIT Actually, I’d like to know if others want me to keep the original Vader’s struggle untouched. I won’t go back on other changes, because those are some of the cornerstones of my edit, but with this…
