Perhaps if you decide to go back to a 480p release, you can encode the HD color corrected work at 480p, and start on that as your master file. There shouldn't be any quality loss, since it's been down-converted from a 1080p source, and it would free up a ton of space, and speed up rendering time, having excised the multiple layers of color passes. Of course it wouldn't be free of further tweaking after the first few passes, but it seems as though it would free up a lot of work.
The thing is, now i've seen what the 1080p looks like and the fact that i can make an AVCHD DVD-9 that will play in its 1080p glory on my PS3 there is no way i can go back to lower res. i'll just have to put up with the slow render rate and the extra space needed. If the HD versions had been around a few years ago the ANH:R would have been HD too (and maybe once the saga is complete it will be)
