Nice, that could work quite well.
I also noticed Sennheiser or Shure released new drum mics at NAMM that come with a laser sensor to detect if the drumskin is vibrating or not. It has a built in gate that only records audio when the drumskin moves so the effect is similar, except it won't filter out simultaneous hits.
