Whether it will be practical to reverse-engineer something like an M7's shutter circuit is another thing altogether. People do this now with the original Nintendo game system. They stuff a small general-purpose computer into the old case and run emulation software. Why they do this is another question, since the part that wears out on a Nintendo, its cartridge connector, is available as a replacement item. All this being said, I agree that it is, and will be for the forseeable future, easier to cut a gear.
