Nice to see that this craziness is in its own thread!
Anyway, my thoughts on the Kyon-ko and male Mikuru (Mikuro?) dynamic would not be motherly but sibling, i.e. since she has a little brother already, an abused male Mikuru would touch upon those feelings better and still keep them apart romantically.
Two other points to make: where (or what) the mole is and how much of a dreamboat bishonen the adult version of male Mikuru would be?
