I got that fishmanlee, I was refering to the notion of having flashbacks while Vader is pondering what to do while Palpatine is killing Luke.

Ressurrecting that idea would be more difficult because you'd have to pull the material from elsewhere.

It could be made as an interesting bridge between Luke leaving Dagobah and Vader arriving at the Death Star if someone put the scenes that way around.
