Here’s my (rough) attempt to implement some of my ideas for the vision, building off of Hal’s edit:
https://streamable.com/v7awjtI very much like this. Is there way to make Luke’s line a bit clearer though? Also, I think you can add on the second " LET GO!" part of Kylo’s line.
I planned to use the full Kylo line, but I feel the last bit really doesn’t fit, and it gets muddled by/distracts from the big lightning blast. I feel “you’re still holding on” paired with the visuals and Luke’s line still gets the point across, that she’s “holding on” from her inner darkness. As for Luke’s line, I think the scream from Rey’s mom would need to be removed, so that should help make it sound clearer.
For comparison here’s a version with the full Kylo line, and Luke’s line made slightly louder:
