The reason I'd like to see a smaller system, isn't primarily due to cost, but so that the system could be deployed closer to where it's needed, and in volume.

The Skynex 35 mm cannon is massive, requires a truck to transport, and presumably needs a generator to power. If you could develop a small man-portable battery/solar powered turret, that fires small-arm caliber rounds, you could put them right next to a foxhole, to shoot down incoming drones. I don't think the electronics should be expensive(by military standards), they have already been developed, it's basically just a timed fuze, that is programed by the gun as it fires.
