I feel, on this point, that we have to pick a side between Palpatine creating Rey/Kylo and the Force creating them. In the canon, the Force is a cosmic power with a will, but darksiders are seen as wielding the Force for selfish ends in spite of that will. So Palpatine manipulating the Force to create life is a very darksider thing to do.
If we look at Anakin’s story, clearly the Jedi had a Chosen One prophecy that the force might create some super-Jedi to bring balance, but we know from implication/word of Lucas that Palpatine created Anakin. It’s a reasonable interpretation to assume Palps did that not just for an heir/apprentice, but because it would set up his creation to appear as the Chosen One and trick the Jedi as it did. And perhaps he still is the Chosen One - the Mortis episodes of TCW (made by Lucas’ choice) do make that more explicit, and he does kinda bring balance. But I think that case is more unique to specifically Anakin/Vader, and may have been what the Chosen One prophecy meant all along - Will of the Force + Palpatine manipulation = haha, still Will of the Force.
But we don’t, in canon, have any such implication of any prophecy about Rey. In the current canon she’s a Force Awakened daughter of Palpatine’s non-force-sensitive hybrid clone son, who becomes one of a Dyad of ‘one light/one dark’ with Kylo Ren. And replacing some of that with ‘Force Awakened creation of Palpatine’ I don’t think brings us any closer to a Chosen One.
We could, I suppose, argue that the Rey/Kylo Dyad is a kind of ‘Chosen One’ together (thouch I’d avoid using the words ‘Chosen One’), and imply that Rey/Kylo are essentially a two-person Vader, a manipulated creation of Palpatine that, nevertheless, is going to enact the will of the force to bring balance. And that’s kind of cool - if probably far too convoluted to put onscreen.
But we could lean into that idea more elegantly:
“Rey, I learned the rest of our story.”
“Tell me.”
"Palpatine influenced the Force itself into creating life. First my grandfather, and then you. Both were once his chosen heir. You… are a rightful Palpatine.”
"Now, the Emperor wants us to fight each other, so that the strongest of us can inherit the throne. But he doesn’t realise that we are one, Rey… Bonded in spirit by the raw power of the Force. We are strong enough to end him and the Sith, and create a new order, together…”
