When the title was first revealed, I assumed it referred to A) The rise of the Skywalker legend, with tale of Luke’s heroics spreading throughout the galaxy and igniting the spark of rebellion, and B) Ben Solo, the last Skywalker, rising from darkness, like Jake said. I even considered the idea the film would’ve revealed that Luke ascended to a higher plane of the Force, where he could interact with the living more directly, as if he rose from the dead. Either way, I think if those first two plot points I mentioned were kept or emphasized more, then the title still works.

I know some other people speculated that Skywalker would be the name of the new order of Force users that came after Luke, which would’ve fit the naming convention of the final trilogy films even more. Even if a person wanted to establish that, I don’t see how it could be made apparent within a fan edit. Interesting idea though.
