Nothing glaringly jumps out to me there, but it’s been a few years since I last fully consumed the show. Once you start producing edits I’m sure I’ll have some feedback. Your plan seems sane and I’m eager to see it begin to materialise.
I get the lack of the Order 66 arc in the Mando cut (since it relies on the previous Domino Squad material and that’s a slippery slope to just turning the Mando cut into the Quality cut…) but how will you deal with its ramifications in the final episodes (Rex’s recorded message about Fives)? Just leave that as it is, since it sort of explains itself anyway?
Also, will you be producing different edits of the same arcs for various cuts? It’d be more work but allow some more flexibility for each cut.
I’m happy to produce a few edits for arcs which won’t take much more thought than just cutting out the intro and credits and maybe overlapping scenes from adjacent episodes a bit.
