I think you are over thinking this. With a properly sized 30 amp feed (hot) you only need a similar sized Neutral. There is never an opportunity to get 60 amps since the circuit is just "paralleled" in the adapter. (like hooking up your service line to a string of duplex outlets in the middle instead of an end.)
