I'm quite sure the method could improve the usable range under those conditions; the dynamic range of the actual sensor is essentially a direct function of the noise, isn't it? However, I also suspect that these conditions were not really taken into account when the bit depth was chosen, so the dynamic range would not increase beyond the one associated with 12 bits - if you know what I mean. (When we discussed exposure setup etc. I while back, I speculated that sensor designers might be "defensive" in the sense that they chose the A/D so that its full range would be usable even under worst-case scenarios, but based on information I found on the net, I concluded that they aren't.)
