Rams don't give good wool quality, but wethers do. But he would need a proper diet in order to get the best wool quality from him, and the best way to achieve that is from good grass. If you can't do grass then he would have to have dry food, but as you can't feed goats and sheep the same feed then I think you are just making life hard for yourself and for him.
My vote would be to eat him, soon.
