If it is logically consistent for a mathematical object to be instantiated in a universe then it is instantiated there.

This so silly it's hard to know where to start.  Even Tegmark gave it up and retreated to all computable universes.  Just think of the infinite number of kinds of elementary particles that could logically exist.  Any two propositions X and Y are logically consistent unless they imply Z=not-Z for some proposition Z.  There is no logical inconsistency in a flying pink elephant existing right now in my den beside me. But don't see one. Better have another Jack Daniels.
