Why not just assume the wf collapses by an as-yet unknown process? Then, unlike MWI, you have a theory within the realm of testable physics and no need to explain where the energy comes from to create those other worlds -- uncountable in a simply slit experiment -- or what part of another world needs to be created to do these other worldly measurements? Is collapse so repugnant (how so?) that one has to grasp at a cure that ostensibly is hugely worse than the alleged disease? Inquiring minds want to know.
