ZoneV pretty much said it all. The sensor is much thicker than film so you cannot just fit it in the same location. Assuming you remove the rear door and replace it with a sensor module that would make it thick and stick out and basically make it an odd configuration.
Tolerances would also be worse as the body and fixings of the rear \"door\" would not be as rigid as a body with a built-in sensor. So what was it then, your lens that is front focusing or your sensor that is not sitting properly or your nose pushing to hard down the sensor cartridge for that shot?
Then you have to find space for the battery or a modification of the old film camera to get power from the existing battery (if sufficient) to the sensor. You also need a modification to sync the sensor with the camera shutter. So basically you need to modify the camera sufficiently that you might as well buy a 5D/D700 and be done with it. And after you modify it, you just did it for THAT body only. So it is not going to be easy or cheaper than getting a new dSLR. At least not with current-day technology. Maybe if they make sensors film-thin and then you still have the power and interface issues.
This \"modular\" approach works very well with larger format cameras though, as they were already built to have replaceable film backs. There are digital backs and adapters for pretty much every medium/large format system that has a removable film back.
