I'm not sure what you mean. How does it differ from what I suggested?

That's one way to get nice probabilities, although I don't like it because
you have to specify the transtemporal identity of worlds, which can't be
derived from the quantum formalism. Another possibility is to say there is
no transtemporal identity of worlds, and use a theory of personal identity
that does not depend on such world identities. David Albert's many-minds
interpretation should also work, given some theory of transtemporal brain
