B3 sounds very similar to A and so I think that symmetry proves that they cooperate together. If we modified A not to require that every action had a provable utility, but only that one action had a utility provably as big as all others, then I think it would cooperate with B2.
I think your conclusions can be right, but the proofs are vague. Can you debug your reasoning like you debugged mine above?
