I think the problem with that is really that his black leather ROTS garb looks to dark and evil and out of place on an old guy. My opinion is just to make a version with Hayden and one with Shaw. As someone who grew up with the Prequels and SEs and saw them in order 1-6, having Hayden at the end of Jedi was really powerful for me and gave a sense of finality to the saga. However, I completely understand that someone who grew up with the OT would feel the exact opposite way.

Also in regards to the hologram conversation. I think, as it is, The tension between Vader and the Emperor is not apparent enough. Vader wants to join Luke and overthrow the Emperor while Palps is tired of having a Nerfed cybernetic apprentice who needs life support to breathe and sees Luke as an oppurtunity to have a pre-Vader Anakin. the scene should not show complaince but uneasiness. The new version tried to fix that but failed miserably. I'm working on a not so great Internet connection so I haven't been able to download any of GM's versions yet but they sound good.
