I also agree that the OT should not be modified to fit the PT. Any unevenness exposes the flaws in the PT, not the OT.
And while it's getting ahead of things, I've always hated that Boba Fett 'dies' in ROTJ. Best to leave it open to the potential for his survival, as he does in EU stories. There is no reason to step on those story lines. As I understand Adywan's philosophy, this is about preserving Star Wars while refining the technical and fx side of things, not rewriting it (at least not the OT).
[ROTJ was terrific. Jabba the Hutt, Yoda, Boba Fett, another Death Star, Admiral Ackbar, the Emperor, good story line...and yes, I even liked the Ewoks. Could the battle have been orchestrated in a more believable and realistic manner? Yes. But as Yoda said, "Judge me by my size, do you?"]
