Actually, you'd could use this technology to give you amazing dynamic range. Let's say all you cared about was ~7.5 megapixels. Well, take the 120mp sensor and carve it up into 4x4 tiles. Assuming a Bayer array, 8 of these sensors will be green sensitive, 4 red and 4 blue. OK, now change the filters on these sensors so that they scale for different levels of light (not just wavelength). You now have four times the dynamic range in red and blue, and perhaps even more in green (you can trade off perceived resolution for dynamic range in the green sensors).
