Possibly, but not recommended. The Schottky diodes allow the power source with the highest voltage to flow current until it's voltage sags below the voltage of the second source. Then they 'share' the current requirements.

One of these(Silicon power Schottky diode) might work, although I'd prefer something a little beefier.

Done properly, it's not too dangerous, but done improperly could be catastrophic. That's probably why FIRST doesn't allow it.
