Yeah, I think you could leave the crawls and the title, but just remove the episode number.

Honestly it’s not a big deal, and you can just overlook it when you watch the movies, but if were to do edits of the movies (even if it just a few little things in ANH and ESB), I would just go ahead and remove them. That way, you could watch the film’s chronologically, release, Machete, or watch ROTS and TLJ as bookends to the OT, and there’s never a question of “what about episodes 1 and 2?”
That’s not even including all of the fanedit combos people could make.
