Now that’s a good idea.
Edit: It would be difficult though to construct the lines for Kylo, all instances of him saying the word “grandfather” are with his mask on.
That brings me to the helmet.
What if Kylo had his helmet on for his scenes on Exogol? Since in the film he reconstructs it for no apparent reason, in this version having him reconstruct the helmet right before he leaves for Exogol would add some meaning behind it.
