> Suppressing pixel readings is not plausible with the current CCD designs
Better than suppressing pixel reading would be suppressing pixel changes. The first process lets pixel to change as a result of incoming photons, the second one maintains the "unread" state.
Yes, current CCD devices can't do that. Advantage of this change is also in reducing crosstalk - if we need, say, to remove accumulated charge and for that we need to draw the current, the current may influence our reading of neighboring pixels. I'm tempted to look towards "smart mirrors" - MEMS systems, even for mirrors of 1 sq. micron - but purely electrical solutions might be possible.
