It should be possible to export the drum track out to a midi file and adjust the individual parts "hi hat", "snare", "kick drum" etc. pull the midi into a daw in the midi file each part appears as a note on its own line. Kick drum note C, snare maybe D and so on. In Sonar for example it is very easy to adjust the overall velocity of a part or the entire kit (or indeed volume if preferred). It is also very easy to randomise velocities within a range. I imagine most daws would have similar features.

Just a thought
