The fundamental issue with a (vanilla) Rey-nobody edit is the absence of an engaging inner conflict, stripping Rey of any compelling character arc (not that Rey Palpatine was compelling, but at least there was conflict.)

Rey accepting her self was already done in TLJ. “I’m Rey, just Rey” just won’t cut it in this context. If TLJ was about acceptance of identity, TROS should be about coming to terms with the darkness within. Integrating the shadow.

Rey: “I saw myself on the dark thrown, I won’t let it happen. I’m not leaving this place, I’m doing what you did”

Luke: “I was wrong, it was fear that kept me here. What are you afraid of?”

Rey: “Myself”.

In a Rey No-one edit that fear has to be justified to Rey as well as the audience. Yes she’s superpowerful and yes she used force lightning, but that should be the tip of the iceberg, the superficial aspect of that fear.

The audience must feel a sense of dreaded inevitability, that Rey, if left unhinged, will turn to the darkside. Who she is, what she has done, and what she is capable of should all point to the same direction.

Rey’s connection to Palpatine must also be tackled. He’s the big bad, she’s the protagonist. He wants her alive , she wants to kill him. There needs to be a connection there.
