Unless the other race is Dunmer, it wouldn't make sense. The AD is driven by the Altmers' goals, which revolve around the subjugation of anyone who they see as inferior. And they see all humans and Betmer as inferior. It would be like a band of Jewish soldiers joining the Nazi army. The only faction that it would really make sense (lore-wise) to join instead of the default faction is the Daggerfall Covenant, as their goals are basically to make everyone equal and bring peace back to the land (EP just clings together for mutual protection, but someone wouldn't leave their own people to join another faction that doesn't really have any philosophies.
