The end of ROTJ will have new music, that's a guarantee. The Ewoks and Lando's booty dancing will be scaled back.... Probably no Gungan celebration... And it will include a short, closing narration by Ian McDiarmid at the very end. I also want the final shot to be of the ghosts...(the original Sebastian Shaw version) instead of the ridiculous "family portrait with the Ewoks" shot.
As for the ROTS scenes: The Death Star scene is being bumped up to the prologue in the very beginning of ANH. The creation of Vader and Padme's death I don't want to go into details about right now. We're trying a few different things with it, but if it works, it's going to be beautiful.
The adoption of Baby Luke and Leia will happen right before Luke burns Vader's body...(if we can get it to work.) I like it there because it's cyclical. it brings you right back to ANH at the very end...making you want to watch the whole thing over again. We might include Yoda landing on Dagobah too...we'll see how it fits.
