Where the saturated full-well electron-charge storage capacity is a function of photo-site volume ?

Not really. The 'well depth' people talk of isn't a physical depth, it is a 'depth' in electrical potential, so that part of 'volume' has little to do with it. Nor, strictly, does the area since the capacity in an active pixel sensor is usually set by the output swing, thus conversion gain, thus the area only of the charge collection electronics in the pixel.
