I had a theory a few seasons back that Hexenbiests were wesen on technically. Based on the evidence of spirits existing in this universe, the only species of wesen we've seen lose their non-human parts and their corpsy appearance, I suspect that a Hexenbiest is really a human that is possessed by a spirit at birth. Possibly an ancesoral spirit, maybe older ones give Hexenbiests more power.

Said spirits can be excorcised by the blood of a Grimm and a spiritless Hexenbiest can "adopt" the spirit of another. Renard is able to be a half-Zuaberbiest because he lacks this spirit, but still has the ability to woge to an extent. Diana may have been chosen as the Zerstorer's bride because she was a "pure" Hexenbiest, in that she didn;t have nor need an ancestor spirit because she was powerful enough on her own.
