With a beautiful tank like that I'm not sure what I would do in your position... whether I would try and divide it or just scrap it and start over.
Actually what I would do is buy a red tail boa, put it inside that gorgeous tank, and then put my balls into rubber tubs in a dark spot with low human traffic. Boas make really nice display snakes whereas ball pythons are really shy and prefer to be secluded and alone.
