yes, i think drumagog has midi output (if it doesn't, others do). but, like fredrik said, it'd be very tedious->impossible to do if you don't track the drums on individual channels.
If you spent some time with it, I'm sure you could do it--you might have some luck by filtering so that different frequencies trigger different hits--good luck with that!! Plus you have the problem of the cymbals sounding like shit. Unless you landed some unique, ghetto early Iron Maiden recording I'd just rerecord the damn thing.
