I like the word play of what I suggested. The two won’t take the throne for themselves, but they instead take the throne away from him.
That would be funny, again, since both Force Sides have prophecies that didn’t pan out.
However, for the book “canon” seems a bit wonky since Palpatine was wanting to have Rey killed by Kylo/Orchi … so was Palps working “against” the prophecy or something? It is a bit murky at best. (I kinda ask this but not really care since I don’t care what outside sources say on things, only in the movie counts to me. Personally. 😃)
I do like in Hal’s version trying to really leave Palp’s motivation/decision making up in the air and can be interpreted by the listener however.
