Two thoughts/ideas.

Would there be any way to implement the Wayfinder and/or Exegol in the Last Jedi? Maybe Snoke knows exactly where it is but won’t tell Kylo until he worthy of the dark side.

Is there anyway to edit the Phasma and Finn deleted scene (other than cleaning it up) to make it look as if he force pushes her, not knowing that he could do that, instead of shooting her? It would give some connective tissue to his arc. I always felt like he was force sensitive in TFA and very obvious that he in ROS.
