If your edit goes like this:

Vader on DS2/Luke and Yoda/Jabba's castle introduced and Chewbacca dragged in by a bounty hunter/Luke and Ben

Then the effect is that Chewbacca's capture seems totally ligitimate. It's clearly not part of Luke's plan, at any rate. It's not like he's waiting around on Degobah knowing that Chewbacca and Leia are launching a doomed plan. Stuff is happening that Luke is unaware of.

It also will be interesting to see Luke learning that Leia is his sister right before we learn the bounty hunter is Leia. That's another example of the kind of thematic idea that's in ROTJ, but never made use of.

This new order of scenes has so much dramatic thrust now that Luke knows up front that he has to face Vader, that he's in danger of falling under the Emperor's power and that Leia's his sister. Everything else has more weight and cohesion. Everything is part of Luke's story this way instead of having a 25 minute short film about Tatooine before the main story actually begins.
