Here is the rub: Grain is an individual. Pixels must align to the grid in order to be addressed by the circuitry. Grain don't need no stinkin' circuitry (random positioning). We'll need intelligent pixels to accomplish this. Probably on someone's drawing board now. Frankly, digital error correction blows my mind as it is now. A grid-less random electronic imager may not be as far off as we think. I thought Maxwell Smart's rotary dial shoe phone was cool, but we jumped right past that without even a prototype!

I can tell you how it could be done in principal, right now. For each exposure, bracket the ISO to get more bits of luminosity informaion. The multiple exposures will align each pixel a bit differently due to camera shake (which can be detected and recorded along with the image).

Stich the whole mess back together with NASA like software, and you have far greater resolution than you could get with a single exposure.
