Great idea! Wonderful execution! If I may… I think it would be great if there is a way you could add a clip with R2 and 3PO. Below is a scene from AOTC where 3PO tells R2, “for a mechanic you do a excessive amount of thinking.” There is enough dialog from 3PO to make him say, “For a Wookie you do a excessive amount of thinking.” Then you can do a cut to R2 and just having him doing a silly chirping noise like the link below. In that way they’re all together and all four of them are giving Chewie a hard time. Just like a bunch of siblings.
My thoughts are you see Chewie thinking then it cuts to 3PO and he says his line, then cut to R2 making a silly chirp noise basically agreeing with 3PO, then we cut to Poe and Fin. Thoughts?

This edit helps cement the idea that these people are a family now, instead of Rey being completely alone on a desert planet at the end. Her friends are there waiting for her : )
It also helps explain why BB-8 is there, he’s just a curious little friend : )
