The FWC of the individual pixel cannot be changed, but when you group (‘bin’) them (like 2x2 or 3x3 together), you can get increased FWC of the larger ‘super-pixel’ while still having the penalty of the single pixel read noise, if the binning is performed in the analog (charge) domain:

So this would indeed make a nice, always on hand pocket camera for capturing decent 12Mpix raws
