I also wonder if it’s sacrilege or not to merge some of Andor and Rogue One? I think it would likely put people off, because it’d make this edit only compatible with itself, and I don’t think these would necessarily add value, but still, I’ll put it here for consideration.

I’m thinking around areas like:

Introducing Krennic/Jyn earlier. There might be a place where the Rogue One opening scenes of Krennic hiring Galen, and Jyn fleeing until her discovery by Saw Gerrera, could be placed as a flashback bridged by present day Krennic and Saw scenes. That’d leave the flashback of Jyn as a child on Coruscant in her home with Galen and Krennic to work as the dream-flashback in Rogue One to remind us that this is the same character, and bring us back to the present. But likely, this idea wouldn’t work as it’d leave us multiple movies before returning to Jyn.
Introducing Bodhi just a little earlier. Perhaps in the final arc of Andor, when we’re talking about Saw definitely being on Jedha, having Bodhi captured by Saw’s group, and then interrogated by Saw, in that episode. But again, probably not a value add.
Shifting the shot of Bix and baby Andor to the very end of Rogue One, just pre-credits, as that final spark of continued hope.
Maybe a couple of other scenes from the Andor finale into Rogue One, the ones that lead into the Tivix plotline.

…but I’m not super excited about any of these ideas, as I say, they’re just here to be considered.
