Wow, crossed feelings about this. On one hand, I fully support your decission of optimizing the times of work in order not to loose time, as this means more Revisited, more material, more updates, and thus more donations and eventually, more followers.
On the other hand, your OT work has very clear goals. Keeping aside ROTJ:R, which allows more space to play, OT:R is pretty much an intervention of brilliant technique centered in audiovisual changes/improvements.
Even ROTJ:R is included in this, for it is the closing chapter after two untouched episodes, and you (and we) know what would be happening in the end of the movie, so whatever plot changes you will be doing on this one, they will be done in an evident direction, reassuring the quality of every creative decission made.
But with PT:R, I hoped you took your time to think, to design (or re design) the structure of the films. You've posted several things that will be in/out the movie for granted, though the thing with the PT is that those movies are such a mess that there are plenty of choices to be made, of which your tips are just the beginning. And since you have top-notch abbilities to sort out a lot of challenges, it would be a shame if you hadn't explored all the possibilities both plot and visually wise. What I'm trying to say (and my english isn't helping) is that you can "make" the revisited OT on the road, because it has linear parameters (I'm not talking about the logistics), but you would need to stop and think about the prequels as an organic thing if you are to really squeeze something good out of the existing footage. Therefore, I'm not sure PT:R could be "made" without being designed.
I don't know, I always thought of it as a different moment in your production, with new and different challenges. Before I say this, I want to make as clear as I can, that I understand these edits are your babies and no one else's, so I don't mean to plebiscite your decissions at all, but I think an interesting thing to do would be to unfold your work into PT:R plot and visual "ideas" while you work in ROTJ:R, and then, after Jedi is out, make a retrospective re-evaluation of those plot ideas (and their feedback, would you let us fans suggest plot wise?) and start on proper work, centered in the visuals just as OT:R is now, which isn't so experimental.
