Yes, that's was where my thoughts originated from. Not only BB but Hancock's attitude in the war surely must have been reported to the Fleet Admiral (most likely whistleblower = Smoker). Though Mihawk did not do anything but him withdrawing when Shanks arrive certainly could be classified as a disciplinary offense towards Marines.

And your last statement could also be possible, but seeing what has happened, I doubt that is of much threat to the shichibukai individual, if at all.
