This might be a dumb idea but would it be possible to just lift the scene of Rey watching the ship liftoff in the TFA trailer/TFA and use that as Rey’s parents leaving? That way, you can have two different ships for Ochi and Reyrents.
That’s not a dumb idea and it would probably be the best option, unless you go with SherlockPotter’s suggestion or if you want to bank on Dom’s idea. I think some people might be reluctant to change TFA for TRoS’s sake, though.
Yeah… I honestly hate how TROS is so fundamentally broken that people have to go back and change both TFA and TLJ to make the trilogy seem more cohesive. 😕
