No, its very risky keeping males together. Your two are probably a once in a lifetime thing. Even keeping a male with a female can be risky.
If you want to keep bettas together, I reccomend a sorority. All you need is a ten gallon tank, and you can put five girls in there, but nothing more or less. Less will raise aggresion levels and more will be overstocking.
Whenever you keep fish together, its a good idea to keep another empty tank ready and on hand. That way, if a fish is sick, stressed out or is being a bully, you can put it in there. Your male, however, sounds to aggressive to be housed in a community tank.
