There is no way that I'm familiar with. Your best bet, as said above, is d3. It doesn't combo, but it prevents most pokes.
BS2 is just in an unfortunate place right now. Even BS2ex isn't that great except in the corner, and even there it barely gets you an OH/low knockdown from 22 or bf3.
BS2 is always a risk, and I don't see that changing.
