OK, well I feel dumb now. Lets start again.
I was looking at your list of changes and noticed you were thinking of having the rebels arrive in a Rogue One esque shuttle. I also saw that your preferred viewing set did included Rogue One (which I assume means you liked it) which is why I would like to suggest including a shield gate above Endor. My reasons for this are:
One, that It always seemed odd that the rebels needed clearance codes to lower the Death Star Shield so they could land on the planet.
Two, it seems to make far more sense that there was also a planetary shield (similar to the one above Scarif) which protected the shield base form orbital bombardment.
Three, there have been people that say that the detonation of the Death Star II should have caused massive debris and an extinction level event on Endor. which the presence of a shield which isn’t destroyed during the battle, would prevent.

I feel that this would tie in well with Rogue One and further cement it as part of the universe. I looked at the sense and I don’t think there would be an issue with any of the dialog, it also might make good explanation as to why the proton bombs dropped by the Y-wings resembled fireworks rather than destroying the ewok village (if of course that isn’t a part that you are cutting).

The only other suggestion is for your HD version of A New Hope: Revisited and that to replace the planet you had the Death Star hovering over, with Scarif. Other than that its all waiting hoping from me, and may the force be with you, always.
