Don't forget that 5 µm is not even pixel size, but pixel pitch only. After space for wiring, it is probably more like 4 µm vs 5 µm. So the difference should be even bigger. > 50% I would guess.

This is fixed with micro lenses.

And dont forget that 15 MP is 50% more pixels than 10 MP. So - more noise per pixel is going to be averaged out. So - the noise per area sensor is not going to increase - not much at least. Unless .... 5 um is the point where the Foveon sensor breaks down and noise starts to dominate. It is when you reach this point you shall not make more pixels. And --- as I have said before - for Bayer CFA this point is 1-2 um for ordinary sensors and 0.5 um for back lit sensors.
