Sony A7 Sensor In a Leica M3?

Ollie Baker, who has made previous Frankencameras has started a Kickstarter project to fund his latest project - to develop an easy and reversible digital conversion on a Leica M3, utilizing the sensor of a Sony A7:

I will be placing a digital sensor within the M3 with all the circuitry and electronics it requires to work. The sensor will probably be from the Sony NEX-5 but if I can get enough funding I will try to use the the full frame Sony A7. I am planning to make two models, one with a the camera's LCD for viewing photos and adjusting settings, and the other with only an ISO dial.
