I'd even go so far as to say I don't particularly mind ghost Hayden at the end, so long as it was consistent with unmasked vader. (which currently it isn't)

I think the only reason I hated seeing ghost hayden in the dvd release was because I hated his portrayal of Anakin in the prequels - something a talented editor can hopefully fix to a degree.

Of course, the preferable route would be to go back and reshoot prequel Anakin with someone who looks like a young Sebastian Shaw, rather than changing the OT. Damn Lucas for making his own saga so damn inconsistent with regards to who he considers the main character of the series!
