Yeah, you could probably pull the appropriate wires and rig up a switch. But operating this could create a distraction while you are driving that could lead to a lot worse than a ticket or a shop bill. And realistically, it will take you nearly as much time as it would to get a replacement stalk from a junkyard, pull the wheel and do it right. Get a good book for your car that shows how the wheel comes apart, then rent or borrow the special tool kit from your local auto parts store. With the tool in hand, and a good diagram, it will not take you that long to change it out. Be careful to disarm the airbag as described in Chilton'* or the factory service manual before you start fussing around the wheel.
This work is not easy in the cold, but if you can start the car and run the heater for a while, you can warm up the parts and stay warm yourself. I would advise against trying this with cold parts. Plastic gets pretty brittle in this weather and the wires you will have to handle will be very stiff.
