Those are pretty good and interesting guesses.

In the recent Q&A, they explained basically how Faunus genetics work by giving examples:

Dog Faunus + Dog Faunus = Dog Faunus

Dog Faunus + Human = Either dog Faunus or Human

Dog Faunus + Cat Faunus = Random Faunus

Also, the plural of Faunus is Faunus. The word has been used for singular and plural many times in the show.
