Not necessarily. Anakin would still be selected by Qui-Gon due to his natural propensity for the Force and mysterious nature of his birth aligning with prophecy. By Nev’s new idea, Palpatine’s actions would be why he becomes the moody and impulsive teenager in Episode 2, not explain why his bloodline is so gifted with the Force to begin with. And Rey must have had some natural propensity for the Force like Anakin to make her a viable candidate for Palp’s darkening of her, so to speak. So you still have to deal with powerful bloodlines created by the Force regardless. The only difference is in my current idea Palpatine is the one that actually wants the Force to make these bloodlines, and pushed it into creating them in the first place. Which explains significantly more in Star Wars canon, and doesn’t conflict with anything, as I’ve stated in my previous posts on this page.
