Unfortunately your entire argument was based on a flawed premise. Bayer interpolation increases the CoC on the film by at most 1/2000" with the *ist-D sensor - it doesn't spread across large sensor areas. And that's a maximum; realistically you can count on maybe half that. That means the CoC increases by only a small percentage, so the effects of the digital capture process are (as Herb and others have noted) only second-order effects, not the dominant cause as you seem to suggest.
