We are not talking about converses here, but negations.
Using your notation, 1 Cor 11:5 may be denoted:

        If A and not B, then C.

The negation usually inferred from this is:

        If A and B, then not C.

The negation of the first statement (If A and not B, then C)
is techically: if not (A and not B), then not C. This may appear
as either:
        If A and B, then not C.
        If not A and not B, then not C, or
        If not A and B, then not C.

Any of the above three are negations of the original conditional,
and may not be inferred from it.

That B and C both involve the head has nothing to do with affirming
the truthfulness of the negation.

I would not call such a misinference "stupid," just an oversight.

If any wish to continue this discussion, we should probably do so
