There are pretty obvious technical reasons why this is impossible.
The front-to-sensor distance is fixed (lens register has to be 27.8 mm to be compatible with M lenses).
The sensor-to-back distance is always going to be bigger than with a film M, simply because the package "sensor assembly plus circuit board plus body shell" is necessarily thicker than the package "film plus back door"
In other words, there will never be a digital M that is as thin as a film M.
