I just implemented moving Chewie’s reveal to after Rey senses him, and the evil Skype call to where the Chewie reveal used to be. It seems like a very natural set of transitions, story wise and with the A/V.
You hinted at changing dialogue somewhere. I just began the Chewie scene with the blast door opening, skipping the coy and now out of place “so, we uh… found a cool… prisoner” part. I used a stock blast door sound effect to lessen the bleed of the music from the lead up and it seems natural to me.
