Although I'm optimistic that it is possible to build such a muon camera. The project is much bigger than I imaged, despite the small aperture size the cost and time required. This project is significant and so I'm unlikely to have this project close to operational any time soon without additional free time, financial and complex, FPGA, software development support. Here is an overview.
Along with the above compound muon camera there will also need to be precision GPS location and time stamping information as more than one location and camera will be required to provide suitable resolution.
