Gosh there are a lot of posts here, so I am probably repeating (sorry) but two things that stuck out to me in the list that I think you should NOT do:
Ewok eyes - they SHOULD blink. Greedo and others got to blink in revisited and it’s arguably a more important feature for the “lovable” Ewoks
The Dug in Jabba’s palace - I think it should be kept, similar to putting in the shot of the battle droid in ANH, it’s good for connecting the prequels texturally (or whatever)
I’m not against blinking Ewoks, but the Blu-Ray ones look creepy and unnatural.
As for the dug, it doesn’t make sense simply because it’s the only creature that isn’t asleep, and that scene kind of relies on everyone being asleep for Leia to sneak in unnoticed.
