Here's an idea I had for both ESB and ROTJ but it might be too radical for this edit and it would comletely screw the EU but I would so like to see it. Here's the basic premise: Make Endor a Moon of Coruscant. Make the planet under the Death Star in ROTJ Coruscant, as seen in ROTS, with Endor visible far in the distance. In ESB, after the Hologram scene, have the Emperor cackling at his office desk with a cloudy skyed gloomy Coruscant cityscape in the background. Have stardestroyers visible in the atmosphere and TIES patrolling the city. A partially completed Death Star could be seen in the distance in the sky of Coruscant while the Emperor gazes at all of the destruction around. Elements could be composited from the ROTS deleted scenes, ROTS and ROTJ. The whole thing just seems like a great way to tie the OT with the PT and add whiz bang effects without cheapening the OT. The TIE attack and the new death Star reveal made ANH Revisited as much as all of the little tweaks did. I hope ESBR doesn't become the Purist edition. I can see how this could all be hell to do but even just adding Coruscant in ROTJ would be enough.

Other suggestions:

Make Dagobah (as viewed from space) look like it does in the ROTS deleted scene. I know it's better to make the PT match the OT but Empire Dagobah looks like it could be Hoth for god's sake! It's just so blue and washed out.

Give the head of Luke seen in Vader's mask on Dagobah sith eyes. I think that could really enhance this scene

I'd also like it if you could keep the one SE shot where the Wampa is flailing with his arm cut off. After Luke already defeats the Wampa there is no need to keep the tension and it would be like a little "reward" for the viewer to see the whole Wampa. You'd have to fix the Wampa's face to match earlier shots though. Trash all the other SE Wampa footage though
