If you get as far as allowing that the other branches are conscious—no, simply that you even HAVE branches, and they should be related by probabilities that don’t change retroactively—then you have been granted sufficient grounds to derive the Born Rule.
It’s getting that far that’s the hard part.
EDIT: I’ve provided this derivation already, here
Does that help?
