Gave this more thought last night. I think I know how I would do this now:

So I’m aware of at least one TFA edit and at least one TLJ edit that narrows both movies down to 1 hour and 30 minutes each, just about.

I’m also aware of a TLJ edit in the making that makes it feel like the ending of the saga by adding just some bits and pieces of TRoS at the very end (there’s a thread on here for that one).

So my proposition is to simply just combine all of those together, and what you’d get from that is a movie that’s just a little over 3 hours long that’s about one half TFA and one half TLJ, with just some light sprinkles of TRoS at the end.

I think that’d be really cool!

EDIT: One thing I forgot to mention earlier is that doing it this way would lose the explanation as to where Snoke came from. Before TRoS, my “fix” for that was to have Rey faintly hear his voice in TLJ when she walks into the ancient Jedi temple by the cliff and sees that little pool with the mural thing (I always thought that the figure in the mural kinda looked like Snoke). This would imply that Snoke is an ancient being of some kind, maybe even one of the first Jedi ever, who became corrupted long ago.
