The Azuremyst furbolg may be an option. The rest are all dead or controlled by the Horde now in one way or another.
The Tideskorn were freed by a champion of undetermined allegiance. The Kirin Tor element was incidental and wouldn't confer any sort of sense of allegiance to them. And with the Highmountain Tauren and Nightborne already pro-Horde, I would doubt she would try to make a stand that would get all her people killed, especially now that Odyn has left.
