If you keep the cages far far apart you might get away with having 2 males in the same cage.
I just had 2 male chins returned after 2 years. They are in my chin room still caged together and my females just had their heats. They never noticed. Maybe because they have never had a female. I sold them as kits and they have been buddies since birth.
I haven't been able to keep males together in the past, but most were full grown when I tried.
If you could get a young male kit to put with your male and move the cages apart and don't let them have any contact with the females you might be OK. Just a might mind you, you just never know for sure until you try.
The question is what if it doesn't work out for any # of reasons, are you prepared to have another cage?
Then you would have 2 single males.
I'd just get him a teddy bear if I were you.
