Yeah agreed, Your idea of the start is very similar to what I’ve done. I’ve changed the beginning completely and delayed Palps entrance.

My version opens up with Kylos (an edited version of Doms) flashback so from the start we know he’s split. Then goes into Luke & Leia’s conversation where Luke asks Leia to “Finish her journey”. Cut to Rey and Leia/training and then Rey introduces the wayfinder so we get an explanation of what it is before any reveal. Then our protagonists go on a journey and cut to Kylo meeting " hunting for the scavenger" then he finds the Wayfinder and hears Palp whisper “Find me!”. I cut the line “every voice inside your head” as I felt in undermines both Vader and Snoke’s characters and made TROS more about Palp returning now without the silly “I’ve been around from the start” “we had a plan all along” crap.

I’m paraphrasing but that delay needed to happen in my opinion just so it feels like the protagonist and antagonist are hunting for the Wayfinder at the same time and that there’s something at stake at least, without just a massive reveal at the beginning.
