ADS-B, as regulated, is a terrible solution for this stuff. EIRP requirements make it extremely impractical as a transmission solution for small devices, most ADS-B In equipment isn't designed to correctly alert for separation with non-fixed wing devices, and (due in no small part to the very high EIRP), there are concerns about both air-time saturation and management plane saturation (ie - ADS-B In equipment also wasn't designed to track very many entities).
