Thinking about it I'd clamp the hex bit in the vice, then use a builders clamp to hold the pedal onto the bit, then turn the crank arm.
The hex bit should hold the pedal axle stationary, the builders clamp should stop the axle climbing off the bit, and the crank arm should allow you to get enough leverage to unscrew it.
