So I had an Idea recently and although I really don't want to have anymore than I have already had and don't want to over do it but Darth_ender inspired me about Vader not being in the executor and then saying the emperor turns up in the eclipse....
Well my suggestion is this Vader stays in the star destroyer escorted by the other 2 (I have good reason for this) after we see Leia / Boush with the thermal detonator in jabbas palace we would cut to a fly-by of the executor orbiting corusant....
We would then see a shot of a lamda shuttle in corusant atmosphere but like the Ralph mcquarrie concept drawings and show how corusant has changed become more opressed and the Emperors Palace from where the shuttle departs.
We would then see the shot from ESB SE of vader leaving bespin but with the planet changed to corusant and the following shot of the shuttle flying to the executor. Obviously this is the emperor although we don't see him until he arrives at DSII
It would then cut back to night and Leia / Boush creeping around Jabbas palace
It's a bit of a Fan-Service clip but It might add a little somthing...
