Yes, a 1080p edit of ROTJ would be great. I'd like to see some of the deleted scenes added to it like Daneditor's Radical edit. I would like it to still be conservative though like you were saying. Another thing I really liked about Daneditor's Radical version is that he moved the Yoda scene close to the beginning which worked out really well. (Spence did that too, I think)
It would also be good if you could despecialize the whole thing and have it color corrected.
