Yes, it would be possible to do that, but it would require a solenoid switch similar to one used by Ford between the battery and the starter. You could engage the gear drive and press the button switch on the starter, then push a starter button to power up the solenoid and send the battery voltage to the starter. The burning question would be "WHY?"
