Interesting idea, but it would be over a decade before Rey is even born at this point.

I fully support any attempt at removing Leia as the ‘other’, but this raises a separate problem. The ST is based on the canon that Luke and Leia are sisters, so any removal of Leia’s powerful destiny would also have to keep her relation to Luke for the ST to function.

So, if an edit kept Leia as Luke’s sister while downplaying that she is the ‘other’ and keeping that mysterious, then it could work, but in no version of the story do I think that name-dropping Rey would make sense.
