I agree with your ambient theory for a wet or semi wet
ambient design but for a dry ambient  design
displacement doesn't change.
At depth if the pressure in the cabin decrease (out of
air situation) below the outside water pressure the
hull can implode but bouyancy doesn't change. (sealed
upside down bucket not an open upside down bucket  as
you put it)
If the hull implodes/repturers bouyancy  certainly
changes and you crash.
