If it’s stated that Rey was chosen by the force to bring balance, I feel like there’s less risk of her turning to the dark, so maybe drawing some connections with Anakin being the “chosen one” and still turning would be interesting.
Exactly, this is what I was trying to nail down with the dialog. The moment still needs to be a big scary reveal for Rey. With everything that she goes through in the film (being drawn to the dark side), her being told that her upcoming decision will essentially decide if the galaxy would be plunged into darkness or back to the light is a HUGE amount of pressure. It gives her a reason to go to Ahch-To. Her thinking could be that if she never has to make that decision the galaxy would be better off without her.
And yeah, we don’t want it to be that she is THE chosen one, because then she’d know she will make the right choice in the end. Rather, she is chosen by the Force to determine the future. And she should be well aware of how much death and destruction Vader caused.
Also, does Rey have a dad if she’s chosen by the force? Do all chosen ones have no father like Anakin? Rey seems to insinuate that she had a father, but she could just be assuming that. Probably not super important but worth thinking about.
Somebody can head canon it that Rey was an immaculate conception if they want, it could be that Rey’s “dad” just started dating/married her mom after she was already pregnant or after she’d been born. So he’d be her step-father.
EDIT: I think I’ve got his line squared away - “Because he saw what you could become. You don’t just have power. You will decide the fate of the galaxy… The Force chose my grandfather. You’re chosen for his legacy, light… or dark. What Palpatine doesn’t know is we’ve become a dyad in the Force, Rey. Two that are one. We’ll kill him. Together. And take his fleet.”
