As long as you are comfortable with setting up and taking down your hang in bad weather, should have no problems. If you use a pad rather than an UQ, you could even go to ground in a shelter occasionally with reasonable comfort. In the Smokies, you are supposed to stay in the shelters unless they are "full". In theory, if you hang outside a non-full shelter, you could be fined by a ranger. In practice, I doubt this would actually happen.
