Some random thoughts:

In TFA, when Finn asks Rey if she has flown the Falcon, I wonder if it would be possible have Rey say, “Yes, but this ship hasn’t flown in years.” Any ideas on where Rey might’ve said something similar?

In the shot of BB-8 rolling toward the Falcon (the one from the first TFA teaser), it would be cute if BB-8 was making beeping sounds as he’s bouncing across the terrain. Sort of like the sound babies make when you’re bouncing them on your knee, where their tone shifts as they bounce.

This is more of an OT change relevant to the ST: I know some people don’t like the “Godspeed Rebels” lines, but instead of removing them, you could also have an offscreen rebel officer say it at some point in the OT to establish it as a rebel phrase. The only two people we ever hear say it in TLJ seem old enough to have both been OG rebels, so it would make sense for them to say that if it was something they said in their glory days.

I think there is an interesting idea in TLJ where we see older and younger generations working together and sometimes butting heads in both factions, and I wish that could’ve been explored more in the film.
