I would hook some kind of clutch pedal switch up or something bad will happen.
I hit my own 70 Challenger fender when I was helping a friend out on his used car lot. I went to start the car, turned the key, and it lurched forward and hit my own Challenger.
If you do it with your car, worse could happen, could kill a kid. If it doesn't happen to you, it will by someone moving your car for you.
Find a new switch or rig something up. Just don't bypass it.
