Unfortunately, EZDrummer has limited E-drum support. EZD is more targeted towards producers and song writers rather than full on e-drummers. It does perform better in http://www.toontrack.com/product/toontrack-solo/ but not nearly as well as the fully e-drum supported http://www.toontrack.com/s20.asp. Perhaps grandaddy or some other e-drum head can offer any further tips on getting better performance.

And, I know of no way to load EZDrummer sounds into any 3rd party drum module like the TD12.
