Can you drive a Giro II or WO Alt-Az mount?

I had an idea about driving the various Alt-Az mounts such as the Giro II/III and WO Ez-Touch.
I'm sure somebody has thought about this and why it's a bad idea, so fire away 
I have a Giro II mount and really like it, easy to setup, no polar alignment, no levelling, takes massive amounts of weight and zero problems.
I was thinking about astrophotography and how the Chief Financial Officer has decided, for some obscure reason (lack of money?) that I'm not allowed to buy anything else. I then wondered if the Giro II could be adapted to do photography.
So my logic was: - Make a wedge for the Giro II. Clearly it needs to be where I am, 56 and a bit North
- You need to be able to lock the Alt axis on the Giro
- You need to be able to drive the body of the Giro at an appropriate speed.
- Use a webcam to take lots of frames and throw away the rubbish ones (all of them?)
Making a wedge is easy enough, locking the Alt axis is easy as well, driving the body of the Giro is a little more tricky, but belts and stepper motors come to mind. Though also a little friction wheel (skateboard?) might also do for testing the idea out.
I'm not trivialising the effort, and I need to polar align, etc etc, but a) will this work? and b) Has anybody done this before?
What am I missing? or is this one of those ideas that should be tried out?

Rob
