That definitely could be good if you want to keep Rey’s parents being killed by Ochi! I still kinda lean toward cutting that stuff out.

Honestly I’m kinda of surprised you want to cut the Force dyad stuff, because I feel like it compliments your ideas for the Sith throne thematically! And I’m honestly all in on implementing that idea in a future edit. The bonds of human connection being stronger than material greed.

But you are right that it is sort of half-baked as presented in the movie. But I feel like it should be expanded upon to explain things like how their minds are able to connect, and how they are able to pass things physically between themselves. It is definitely beyond anything we have seen before. I think I would just try to set up the idea earlier in the film. My idea has been to try and hint at the Force whispers more in the previous movies leading Rey to the saber and the texts, maybe add Anakin whispering “Rey”, and then in IX reveal/imply that Anakin and/or the Force ghosts brought them together. So earlier in TROS, Kylo has a vision where he hears the voice of Anakin say, “I/we brought you together, a dyad in the Force”. Maybe when Kylo touches Vader’s helmet, or when he picks up the wayfinder. I definitely think it would be nice to set up earlier so we see how Kylo knows about it whenever he tells Rey.

Perhaps you could make it more subtle, but I think using the Force ghosts as sort of a conduit to act on the will of the Force is an interesting way to juxtapose Palpatine’s machinations. There is a hidden battle happening between these two forces. Palpatine manipulating Kylo, Anakin/the Jedi spirits guiding Rey.
