I read this leak/speculation on Bounding into Comics but considering it is Disney Star Wars I can totally see this happening. The working title is also New Jedi Order which leads me to believe it will be giving Rey what Luke's story was in the EU. I love how they didn't want to use it but feel the need to bastardize it. Like that Ahsoka series looks like an Heir to the Empire bastardization.
What would really crack me up would be to see Rey being a grumpy hermit on an island who has given up, and then wait for the critics to call it brilliant and subversive.
Maybe they take the duology away from the force. Was Anakin a transforcer when he turned to Darth Vader? In order to detransition he had to die?
Since you mention alien I'm thinking we get a Jedi Hutt. Perhaps a humanoid one. They would love to cast a land whale.
Lizzo wasn’t enough?
I'm thinking the dude from Linus Tech Tips looks pretty close to a Hutt. He can cut down the Sith for doing unspeakable things like using air cooling on their CPU.
