If you were using bipolar transistors such as the pnp2907 or ones like that you would get moore current but if you used a MOSEFET I think that gives you as much current as the power source supplies. It depends on what type of H-bridge you are using.
It will only blow up if you give each bridge different direction commands.

Wrong way round, a MOSFET would share the load where as a transistor would not. So there is no point in doing it if you have transistors in your bridge.
