My next plan would be to use as much from the 1997-SE (I've got an anamorphic digital broadcast from a German pay-TV-station), including the localized opening logo "Krieg der Sterne" (because since the prequels came out there's always the "Star Wars"-logo in front of the crawl... even on the 2004-OT). Then I'd "just" need to upconvert the 2006-OOT to match the SE (which would probably include some LimitedSharpen and some dirt removal) to replace the SE-parts with their original versions. It's as simply as taking candy from a baby... trained in kung-fu...
