This edit keeps getting better and better. The sense of urgency that is created for the Rebellion is right on track. The only thing that slows this down is on Endor - when Luke, Han, etc. allow themselves to be captured by Ewoks for no determined reason. This has nothing to do with your editing Daneditor, as this was the original film idea obviously. This never made sense to me - to slow down the Rebellion's biggest offensive by being captured. Han and Luke didn't know that Leia was with the Ewoks, so why waste time to be tied up and hauled away?

The only way around this (that I could think of) is to insert quick dialogue from from another SW movie. Dialogue that says the Ewoks have Leia, giving reason for the group to be captured. Example (paraphrased):

Threepio: I do believe they think I am some sort of god. I could be mistaken...they are using a very primitive dialect.

Han: ...why don't you use your divine influence, and get us out of here?

Insert dialogue from A New Hope (Death Star scene) here:

Artoo beeps rapidly

Threepio:...he says "I found her," and keeps repeating she's here.

Luke: The princess, she's here?

Back to ROTJ dialogue now:

Luke: Han, it will be all right. Chewie, give them your crossbow.

SCENE continues normally, with the group being captured.

Interesting idea, but I wouldn't want to include dialogue from ANH. Perhaps there's a line or two in the ROTJ radio play that could be added instead.

As for your general point about how the edit slows down when they reach Endor, it really does. And it's probably my least favourite section of the edit. But the edit is about 1h50m right now, and I wouldn't want to cut it down much more. Actually I'd rather add another 10 minutes, but unless "Tydirium" finally gets released and has amazing content I don't see how I can.
