Why not?
A couple of humanoids
and the rest are tamed creatures, like the Elves have (or like the Kraken in Pirates of the Caribbean)
especially considering how the developers assign units to a faction in campaigns... for example, in Heroes of Might and Magic IV, it turns out that Centaurs are pure Barbarians, they absolutely don't recognize magic, and because of this, they all switch to the Barbarians from the Elves
The idea is good.
