Interesting. So, if I'm understanding this right you could import an mp3/wav drum track, convert that to midi then use ezdrummer or AD2?

Of course not a stereo mix of drums. You really want (at least) your kick and snare on separate tracks for this stuff to work best.
 
Now if all you have is a stereo track it's would behoove you to clone that track two more times. Try to eq out all but kick freq on one and all but snare freq on the other. Bear in mind this method would still likely to give you stray MIDI notes depending on the material.
 
A decent drum replacer on a track with just kick or just snare will do an excellent job of detecting the transients and do an excellent job of replacing that.
 
The drag audio to MID can be hit and miss depending on the source material (GIGO as they say).
