Micro ROV's would be my solution. With the tech today they could engineer them. Maybe the size of a soup can or so. Program them to act auto and to take as many pics/video as they can. Once there done they could retrieve them on the surface. It would only take time and money. They are companies now launching hundreds of micro satellites not much bigger. And my latest smartphone that I bought for under $50 has at least hundreds if not thousands of times more compting power than the puters used on Apollo. Maybe have to have them work in tandem/pairs...one little bot dedicated for lighting the spaces.
