Mapping voices of a drumkit staff to midi channels

Can you create a special drum staff and make it possible to map its voices to midi ouput channels. thus i could attach each voice to a pitch randmizer vst plugin which has several midi-in pairs and audio out pairs and allows to load a soundfont. It will allow to load one drumkit soundfot and get different pitches. thus i can avoid using large external programs like hydrogen. Also, please increase the number for voices for that staff if possible. Though 4 would be enough for now. This will allow to have one staff for the drums instead of having many staves to have different pitches or other variations like velocity,etc and will save space.
