To put it another way, I think they're currently "wasting" a couple of bits for ISO 640 at the bottom, since the read noise seems to be something like 3-4 electrons and the gain is only about 1.

If the A-to-D converter at ISO 640 had a 4x higher gain and the same read noise, then certainly 12 bits would be fine for counting up to the ISO 160 well capacity.
