Other ideas:
Use Finn’s “Noooo!” from Chewie’s ‘death’ to begin the vision, similarly to the way baby Rey’s worked originally, or Finn yelling “Rey!”, though that’s become a bit of a meme.
You have to remove three Finn NOOOOs or REEEEEEYs to add one.
Thinking about this some more, a better option if you’re starting the vision with the TFA duel would be to use Finn’s scream when Kylo burns his shoulder. I think it’s a pretty recognizable yell which would setup the following visuals. In TFA it’s the first thing Rey hears after coming back to, it’s when we switch to her perspective so it’d be pretty fitting, and you avoid adding on to Finn’s signature REEEEYs & NOOOOs in the movie.
