To be honest, I don’t think either of these work. It is just weird for Rey to suddenly be there. Maybe the least you could do is add footsteps before we hear her talk. But honestly I’m beginning to question if trimming this moment is really necessary. Yes I agree with your logic that you want to cut out things that serve no purpose besides being a callback, but going back and watching this scene makes me feel like it does serve some character-building purpose. I think Finn, trying to be ‘cool’ and then just being clumsy/awkward helps Han see that this boy is obviously not a Resistance soldier. I think Han probably was a little suspicious, but when Finn broke eye contact with Han, it basically confirmed it. Which I think is a better character-oriented reason than Han noticing his “Stormtrooper shoes” that the one deleted scene provides.

Have you tried just trimming the few shots that seem to just sit on the hologram? Maybe that would be a good compromise, because I do agree that it might stay on the holograms for just a tad too long, but still feel like the moment does hold some value.
