First off, you would need to completely disengage all windings from one motor to the ESC when you want to transfer power, thus you would need a triple pole, double throw switch. This would allow you to simultaneously swap all 3 ESC outputs from one motor to the other. The other issue is that for it to work properly, you need a switch capable of handling AC current at a pretty high rating. A 540 can brushless motor can pull upwards of 100A depending on the winding of the motor. That makes for a very large switch.

The easier answer would be to use an E-Maxx 2 speed tranny with RC-Monster steel idlers and just shift from 1st to 2nd gear when you want more speed.

You only need to disengage 2 wires to stop power from getting to the motor, so a dpdt switch would work. Brushless motors are DC, so you would need a switch capable of at least 100 DC amps. A relay might be better suited than a servo and switch.
