Word on the street is Trump is already annoyed at the sideshow RFK is creating and may just dump him.
Now, I think some of that is wishful thinking from the media, or them writing something based on loose rumors that they know will get enormous clicks, or something that may make Trump change his mind. But at the same time, Trump is pretty well known for making promises to people when they're useful and immediately dumping them when they're not, and in this case, he'd probably find someone worse than RKFJr, like putting Nick Fuentes or Andrew Tate in charge of it. But it'd still be hysterical for that to happen to RFK.
