Empire Strikes Back is a very different Beast in fact there are scenes that were not created and or filmed cut and re-arranged. The first and third act is where most of the shuffling occurs.

The rest of the films should be simple enough to simply extend with missing shots without any re-arrangement.

I think there are 2 instances of re-arrangement in Star Wars as far as I can tell and those are the the Falcon Blasting out of Mos Eisley and the Death Star landing bay. But they are self contained re-arrangements. I think there is one to do with the pilots too (wedge Antilles) battle of yavin.

Empire Strikes Back is really shuffled up not saying it does not work in it’s theatrical or special edition state but that the context of the film is not always easily apparent and you need to look beyond seeing a deleted scene and look for missing elements that were planned to understand the context of missing sequences and the order of scenes and how things would have been slightly different. Just saying that if you really want to see an extended cut of Empire it would be quite a bit different to all the rest of the films in the Saga in how that works. And it will take a lot of your time trying to figure out what goes where and how it works and not having the footage available to do this also. But the full cut is probably only 5 minutes Longer in a very different order localised to sequences and the overall narrative and shots in a different context.

I’d also suggest not trying to include all deleted scenes or alternate takes.
