Sans bonus material, there are projects already underway to restore the OOT and '97SE, as well as color correcting the BluRays. I'd say bide your time until those ripen and make your own custom box set.

I agree. Wait for Team-1's scans for the OUT or a more complete version of Harmy's despecialized trilogy. If you're impatient, for the OUT, use dark_jedi's GOUT V3 DVDs. That would give you all three in SD. For the 97's, use the TB versions. These are, I believe, either laserdisc rips of SD widescreen broadcasts. I believe there may be a color corrected version of the 2011's out there at the moment.

For TPM, there really isn't a decent HD reconstruction of the theatrical, so you could either use the TB or just the DVD edition, which is essentially a director's cut. Also for TPM, try to find a color corrected 2011 with added grain to somewhat ride the film of waxy looking faces and possible bringing out detail elsewhere. Then just the DVD and Blu Ray versions of AOTC and ROTS. You may also want to include the 2004 versions for completionist's sake, though these wold be SD, and you really wouldn't want to bother with color correction.

For special features, all the bonus disc material from the PT DVDs, all the commentary tracks for each film, Empire of Dreams, The Birth of the Lightsaber, From Star Wars to Jedi, the Definitive Collection laserdisc bonus material, and whatever is included in the Complete Saga set.

This is something that I've been wanting for a while, so it would be nice to see if this comes to light. I would love to see some box set mockups and disc covers as well. Good luck!

EDIT: This may be a good TPM project to watch for this: http://originaltrilogy.com/forum/topic.cfm/THE-PHANTOM-MENACE-THEATRICAL-HD-Toppers-Version/topic/17137/
