I do really like the idea of continuity edits (it’s something I myself have been mulling over, in regards to the OT specifically), but even that can get complicated. Already I’m seeing things that are subjective. Like, the fact that Obi-wan saying Anakin was a good friend doesn’t gel with the prequels, and while I’m sure most would agree on that, it’d be hard to come to a consensus on how to actually fix that.
Smaller and more concrete solutions (like “old friend” instead of “little friend,” which coincidentally is something I’ve had in mind for awhile) seems a bit more feasible. Not trying to discourage or anything of course, just thinking out loud, don’t mind me.
