Let us have double muts such as primal and Piebald (Tovero) or like primal fangs and Charred or Du and primal or siren tail and Cross; it would be nice to be able to stack regular with lethal as well;

only the muts that this won't effect will be Achromia, Melanism, Harlequin Ichthyosis since those conditions rewrite everything so for those muts it will be singular mut only.

let me know if you want more information or to clear up anything.
