What I would do is breed your old male to a female that has the desired traits you are after. Then keep a couple females pups out of that litter. Take the best one and breed back to him.
Just my 2 cents
I am breeding him to 2 different gyps right now. The issue is that while i would be happier then hell i doubt he will make it long enough for these future litters to be far enough along to breed back to him, this is pretty much the only reason his son is still on my yard....insurance if you will
