Finally, bear with me on this last one: I know Adywan intends to restore Sebastian Shaw as Anakin’s Force ghost. I understand why; regardless of one’s like or dislike of the prequels, it was staggeringly sloppy and lazy of Lucas to simply reuse existing footage of Hayden’s head that hadn’t even been aged up to look like a man who’d be in his late forties. Having said that…Shaw still presents the audience with the opposite problem: Obi-Wan standing next to his former student as played by someone a decade older than Alec Guinness. Is there any sort of visual tweaking that could be applied to make Shaw look somewhat younger, somewhat easier to connect with the character audiences know from either the prequels or the Clone Wars? Facial tweaking, more hair, darker robes, anything?

Replace shaw and Hayden with prowse.
Problem solved

Also someone else suggested using the “unseen” documentary prowse as unmasked Vader scene. If that ever becomes a possibility it’s a no brainer.
