We are all for change but only for the better.

Ady is planning a major overhaul of the space battle effects for ROTJ:R, mostly the old fashioned way with models but that's just surface detail.

Without enhancing the story of ROTJ (and the PT) changing the veneer will not hide the fact that the furniture is mostly wobbly and riddled with woodworm.

Replacing the ships with CGI (no matter how good) isn't going to be enough (or in some cases desirable).

So in a sense most of us on here are for changing more than you are proposing.
