Roberto Paolo Riggio

If I were you, I would try it, and if it looks like it would work, keep it. If it seems confusing, try something else. Percussionists don't need to know the specific notes being used in a cue, only the rhythm and shape of the melody, and what instrument is playing it. It's just to help them find where they are. It's really not a big deal. What matters is if it will work or not, not whether or not it's conventional.
