That’s a great impersonator! I’d be hard pressed to overwrite actual JEJ with an imitation, though.
Eh, maybe alternate audio? I don’t know if the guy would give permission but doesn’t hurt to ask.
I think an alternate audio track would be great personally. I love JEJ but this scene rips me out of the film every time.
Alternatively, in TM2YC’s cut, he removes this scene and saves the reveal of Vader for when Tarkin calls on him later in the film. I’m honestly not sure which I prefer.
