It would. But you simply cannot make a sensor that behaves like film from an optical point of view and with existing CCD/CMOS/BSI CMOS technology.
Just to name them, the maximum chief ray angle and the thickness of the absorbing layer are simply not the same... This can be seen in wide angle lenses mainly and usually brings 'more vignetting than on film' and 'worse corner resolution than on film'...
