Here are a bunch of things I’m considering for my v2:

Add Luke’s severed hand to the paraphernalia on Exegol
Lando doesn’t kill the stormtrooper. Instead, his crossbow bolt electrocutes him. This is necessary because later on he says he doesn’t want to kill stormtroopers, which is why he hasn’t been fighting.
Finn jokes to Lando about him being the Master Codebreaker (a change in my other novelization)
The red plom bloom is the last trinket Lando has of his daughter
In the Palpy vision Rey gets at the end, mention that her father escaped Exegol with the lightsaber that came with Luke’s severed hand. This explains why the lightsaber called out to her at the castle, since it knew her father rescued it before. Presumably her father sells it from there and it ends up in Maz’s possession.
Add DJ and his ship, the Libertine, to the civilian fleet. Adds some redemption to his character.
Replace “I’m Rey Solo and this is Ben Solo” in the ending scene with “We’re Skywalkers”. Just makes a lot more sense, and I feel really stupid for not coming up with this before.

There are probably some other things I’m forgetting, but ah well. My TLJ project is nearing completion, so I’ll be working on these things and more when that’s done.
