Yeah, I think attempts have been made over the years to make the Star Wars Vader more like Empire, but I prefer his more expresive, crude version to the refined one from the sequels.

Also, not sure if I’d consider this radical, but I’d open Return of the Jedi with the Emperor’s arrival. Seeing Luke’s introduction as a shadowy cloacked figure would be an interesting paralell if we already met Palpatine by that point in the film. And naturally, it would get rid of the uneventful “Permission to land” opening.
