Is there a song in 6/8 that you want to emulate? If you can import an audio file into some DAWs, you can overlay a MIDI grid on top of the audio and drop in midi where you hear the extra stuff that your drum track might not have in it. Of course the first step is matching the tempo of the project with the tempo of the audio file.

I would be careful making 6/8 too active, however. You might just need to swing it a little, if there's no swing in the beat.
