The smaller the pixels get, the closer to log response dynamic range per unit area you're going to get. That's simple because of statistics of photons registering at random locations. Happens even if readout noise or whatnot increases. For those who doubt: imagine a sensor with so high resolution that each pixel is only being hit by just one photon or none at all. Such a sensor would have the ultimate dynamic range. No burned highlights at all. (Of course you might want to downsample the result before use. :)) Although you seem to be after quantum efficiency and low noise. You certainly wouldn't be getting either of those with the ultimate dynamic range extreme pixel count sensor.
