Star Wars Episode IX- A Christmas Carol?

So spoilers for The Last Jedi, obviously.

At the end of Episode VIII, we see that the remnants of the Resistance escape aboard the Millennium Falcon and are preparing to become a full rebellion; Rey is now the last of the Jedi and has the ancient books; And Kylo has become Supreme Leader of the First Order that is now taking over the galaxy at large.

When I first left the cinema after seeing the film, I genuinely had no idea where Episode IX would go from here, which was odd to me. Almost every Star Wars film I've had a general idea of what would come next, but this one baffled me (in good ways, I loved the film). The Last Jedi almost felt like the end of a trilogy rather than the middle part at times.
However, after taking a couple days to think things over, I think I have an idea of a direction tey could perhaps go.
This may sound a little weird and like a bit of a joke, but hear me out-

Charles Dickens' A Christmas Carol.

So as we know, this trilogy is basically the story of Rey and Kylo Ren, and I definitely think that'll continue in Episode IX, for sure. I think there will be a time jump of a few years so that we can see the Resistance with increased numbers, and for Rey's training to have improved. I think we'll see her transition in a similar form that Luke did in Return of the Jedi. Let's talk about Kylo though.
I very much think we're going to see the phrase 'Heavy is the head that wears the crown' play out. Kylo is the most powerful being in the galaxy now, and yet he ultimately has nothing.
I think we'll see him as the true, unleashed, vicious, tyrannical monster that Luke foresaw in young Ben,and he will for all intents and purposes be the Ebeneezer Scrooge. He'll continue to sink deeper and deeper into darkness.
Luke's dialogue at the end of TLJ is that he will always be with him, and I think we may actually see this play out, Luke constantly whispering in Kylo's mind. If one wants to take the Dickens analogy even further, perhaps Kylo will be haunted by multiple ghosts. Luke could represent his past, they could perhaps use an image of Leia as the present, and for the future, he sees two- Rey and Darth Vader himself.
Symbolism for what Kylo future could hold. He's obsessed with becoming a new Vader, yet what happens when he's physically shown what that could be, and then there's Rey- his one connection left, his one hope.

I do think there's still a good chance of redemption for Ben Solo in this trilogy. Even at the end of TLJ, Luke doesn't Ben can't be saved, just that he isn't the one to do it, and when Leia says she knows he's gone, Luke replies "no one is ever truly gone".

Thoughts?
This is an out there theory, I know, but it's what I've got at the moment.
