I gotta create an account and play with this sometime. Hope the clips help with tailoring it to what we have to work with. But I think we could just replace every single line for Poe in the scene, with two (or ideally three) that have to be dubbed over his face speaking.
Also, I love Leia’s two new lines, “He’s too dangerous,” and, “A Jedi needs her weapon.” However, when mixed directly into the movie opposite other lines of dialogue, I can hear some AI cruft. I would NOT even sweat it were it not Leia in TROS, which had all viewers’ eyes and ears primed to hone in on “Gee, how did they repurpose scraps to contrive Leia being there?” They are short lines, and even if that AI cruft has to remain, I still think they work well enough.
