Right, that would still be the message, but I’d nevertheless need to remove the Reylo kiss because we’d have an instance in canon wherein it would appear that the person who performs such a ritual is biologically related to the offspring. So might as well have Kylo’s reveal be something like:

“Palpatine influenced the midichlorians to create life. First my grandfather. And then you. We… are both Palpatines.”

Even if Rey and Kylo choose to deny Palpatine’s control over them, I doubt they’d be willing to risk making out like that LMAO.
