Since each layer of sensor material is laid down (or ion-implanted, or etched)
in a separate operation, it would be a fairly straightforward matter
to offset the stacks so that light went more or less straight down.
Of course, this would need to be optimized for particular lenses (or
at least nodal points) but is not ultimately out of the question.
Right now, designers seem to be having enough trouble getting the
sensors to function at all, though

Offsetting of the stacks occurred to me too, but that would then
optimize the edges for a wide angle and would not be optimum for a
telephoto which has relatively parallel rays. Olympus may have the
right idea of redesigning the lens so that the wide angle also has
less angled rays. Considering the jump in size from a wide angle
rangefinder lens to a retrofocus one for an slr, a super retro may be
even bigger.
