Use of a multiband compressor plugin may help you here.

Duplicate the drum tracks three times or more and then apply a separate instance of the multiband compressor to each track, set one to emphasize only the kick, another the snare, etc.

This method will have lots of bleedover, of course, it is not going to be like having the pristine separately mic'd tracks, but even they suffer from the bleedover problem, too.

The ultimate for you may well be in finding another Drum generating software that puts the drums on separated tracks.
