I recently had an idea to incorporate Vader’s hallway-scene into ROTJ.
It could serve as a starting point for a completely new subplot about Vader letting the plans and position of the new Death Star slip to the Rebellion, because he knows the Emperor will be there and is anticipating a chance to get rid of him. It would also add another dimension to Vader being stationed on the Executor instead of the Death Star, as well as the Rebel shuttle sneaking past the blockade as all of this might well be part of Vaders plan. And not just to turnLuke over but to destroy the Emperor as well. On a side note, him continuing to plot against his master would make Vaders character more coherent to ESB.
The twist to this little plot would of course be Palpatine revealing his puppet game and foresight.

Appart from this plot idea the hallway scene would further vilify Vader and thus add more to Lukes struggle to save his father and it would plainly give Vader something to do and be the Character he is in the ANH and ESB, as there are no officers for him to choke in this iteration of the saga 😉
