When was it ever confirmed that Lucas’s treatment had Kira/Rey as a Skywalker? I don’t think I’ve seen that.
You’re right. They never truly confirmed if they were Skywalkers, but she’s the main character and George said the Sequels are about Darth Vader’s grandchildren.
JJ and Rian are artists, they have authority over their stories. Your thread is about George’s “Original” ST, which is fair. But all you’re doing is fan fiction. That’s what I’m trying to say.
Sure, they have authority over their stories. But they had to trample the original artist’s stories to write their own, so I don’t think they deserve the same level of respect.
I know this is fan fiction, but that’s not a bad thing. You don’t need to put me in my place. I’m already aware of it.
