Jar Jar! Sounds great! Very funny we posted the Luke stuff at practically the same time LOL. As for the “Leia knew it too.” replacement, how about something like:

Luke: "Because you’re a Palpatine? I wanted to help you; I told Leia.

Rey: “She didn’t tell me. She still trained me.”

Luke: “Because she saw your spirit, your heart. Rey, some things are stronger than blood.”

This implies that Luke (and Leia) only knew after Luke had transcended into the force. Personally, I like the way it is now in V3, but if Hal did decide to add it back in, I think this could work.
