assuming that re tracking the drums is not an option. and the band wants the song mixed as is........
you tracked the project yourself, so you probably don't have this problem. but i get a lot of tracks that were tracked by other people, and apparently they have never heard of phase.
so one thing that helps me get drums to punch, is making sure all the tracks are in phase with each other. and lining up the tracks so they are all hitting at the same time. it is amazing how much of a difference a few milliseconds make in the body and punch of drums. but use your ears and not the wave forms.
i know that people have said that compression will make your drums cut less, but if you are savvy, you can shape the transient of the drum with a comp by playing with the attack time.
also if you are really trying to avoid triggers, there is a piece of gear that spl makes, called the transient designer. i rarely use it, but sometimes its the only thing that will make crappy drum tracks punch.
and after all that being said, we really cant give you any useful advice on your situation without hearing the tracks.
peace,
