I see several millimeters between the film plane and the leading edge of the rear curtain. Surely that is something to work with? If not, a corrector lens could be placed at the LX film plane to alter the plane of focus by the amount needed to fit a sensor to the back. The shake reduction mechanism could then occupy the dial data back compartment. Other circuitry would sit off to the left and in the film cartridge area. A little snip snip could prepare the take-up compartment into another hole in which electronics could be packed. This description and the methodology I release into the public domain. I don't have the time to make it happen! :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) :-) But I call dibs on one of the first production units, please...
