The problem with such interpretations is that they violate causality. Check out Wheeler-Feynman absorber theory for history. Concepts such as collapse of a wave function aren't necessary when you stop treating the observer in a special way and start considering observer-particle as a big quantum system.

Causality would not seem to be broken if the effects were shunted to an adjacent universe. This would directly assume that MWT is indeed true.
