I think that seems possible, it's strange that only humans and ghouls have RC cells.

Although it could be the mutation that led to RC cells only occurring in humans happened first and the ghoul mutation happened to deal with problems like RC over secretion.

The fact that the kakuhou has eight possible locations in a ghoul's body, makes me cling to the theory that kakuhou are symbiotic organisms that need hosts that produce larger numbers of RC cells than the average human.
