HI (I’m new so not sure if this is on one of the lists of NEvEr getting added)

What do we think about mutie “layering” such as having a primal which would be a “posed” mutation with something like overgrown tounge/a piebald! However more complex mutations (lethal /hybrids/dwarfies) wouldn’t be included
Possibly a primal(of all models) exclusive feature and not being able to stack two piebalds spotted and patches(vernal) would technically be taking up the same slot so that wouldn’t be allowed however this could be on a won’t get added list if that’s the case correct me also this chance would be as low as getting a lethal!! And nothing to boost it OR a gmo cow/lion meat exclusive boost however if this isn’t on any list respond yes or no for support and why!
