The base is completely workable but has no mutations - it's just been sitting there since domestics came out.
I'm just not sure how to get it to work with subspecies-changing items, as it might be fairly difficult to work with there. For instance, I don't think I can get Alchemy Shards to work here, unless the parent is already a Primal Dwarf, because otherwise you'd be trying to trade an uneven amount of subspecies at once.
