You will pay as much for a good temperature controller as you would for a used fridge. Also, one corny just isn't enough. Less than fifteen minutes after you first tap is installed you will be thinking "damn, I wish I had a second tap".
Back to the original topic, it could probably work with a temperature controller, but I think you will be wasting a lot of energy. From what I have seen wine fridges aren't very well insulated, especially if it has a glass door.
