I almost wonder if it would be better to have her just see Ben’s ghost in the “just Rey” version and remove the ghosts of Leia and Luke entirely. The reasoning being that Ben is the one who convinced her to “let the past die” and in kind of a perverse way, set her on the path to self-acceptance. Maybe it’s just because we’re aware of the theatrical version, but the way it plays out currently it seems like she sees the Skywalkers, they expect her to take their name, and she’s like “nah eff that- too much baggage”
I could also see a version with just Ben and Leia. That way Ben is reunited with his mother, and we already get Luke’s ghost (along with Anakin and the others) earlier in the movie
