(To preface, I’m not saying this because I want this idea to go either way. If we choose not to go with it I won’t really mind.)
I don’t think Kylo knowing where she is going is any less confusing than the theatrical.
In the theatrical, we can assume Kylo had the dagger translated, I guess. All he knew was that he had to go to Endor. He didn’t have the dagger to figure out where exactly on the Death Star he needed to go, Goonies-style. Despite that, he still found his way into the Emperor’s throne room. That’s never addressed.
With this dagger edit, we could also assume Kylo used the dagger to get a glimpse of the Death Star ruins, just like Rey would in his chambers in this version of the movie. We could even show a glimpse of the Emperor’s throne room itself. So this version would arguably have a better explanation for how Kylo knew where to go than the theatrical version. Or, we can assume Palpatine just told him. The scene where Palpatine speaks to Kylo through the Force makes it seem like Kylo knew where Rey was going without his help, but since we moved that scene, it wouldn’t be crazy to assume Palpatine told him where the other Wayfinder is.
But like Jar Jar is saying, we would need to make it clearer why Rey received a vision when she picked it up on the Steadfast, but not on Pasaana. Maybe if we had Rey say “Show me” or something could help with that.
But if the Auralnauts actually agreed to it, then I think we obviously would have to go through with this, no question. 😂
EDIT: I personally think the vision/glimpses would need to be on the more subtle side, if we did it.
