So, an adjustment mechanism needs to be provided. Also, you need to have it fairly straight, so a small difference in Z distance doesn't provide a shift in the crosshairs. But, such a mechanism could be made pretty small. Possibly hollowing out an end mill holder or other taper shank part (or making one from scratch) would allow the adjusting mechanism and part of the camera to fit up in the spindle taper. Maybe you'd have the adjusting screws just be setscrews tapped into the body of the holder. 6 setscrews in two rings of 3, an inch apart might be enough. You'd then have to pull the thing to adjust the screws each time, but you should never have to adjust it again, once it is zeroed in.
