Sway,

Welcome to MacMod first of all. In order to use another touchscreen there is quite a bit to consider. Drivers, pin out configuration for the wiring and mount points.

Honestly, your best bet is going to be to try and put a trolltouch component over it or maybe even taking the touch component from the waccom. There was another tread on this recently. And there are multiple threads on the trolltouch.
