Can you bypass Genie garage door sensors?

Genie makes the safety beam system very foolproof; shorting the wires to the sensor won’t work at all. The only way I could think of bypassing them is to put both sensors facing each other and mount them on the wall or somewhere near the opener itself. Set the motor force to maximum if you want as well.
