I was thinking this myself, but that will leave OP submitting most secondaries after Labor Day. I'm not in love with this. I get OP not wanting to lose a year, but that's the risk when you take the MCAT in late May and don't like your score. I'd do the throwaway now, and bail on the cycle if the score sucks. IMHO, having a sucky May score, no matter what it is later combined with, plus September secondaries is not exactly a recipe for a great cycle.
