Yes, have done that with adult Alaskan Malamute Females (2) adding a 6 month old CO male (caged for 2 days) then let them mingle in the backyard; he calmed down eventually....Also introduced a CAO puppy to two CO year old females - that was trickier: the 2 CO's were sisters and fought each other, while 1 accepted the CAO puppy and the other was aggressive. Once the CAO matured she held her own though. Word to the wise keep your hand off their heads when breaking up fights: flash bites (even after the dog realizes - Oh Oh! bit my master) go to the bone....Yikes. Godspeed.
