12-bits of color will not increase the number of stops of light your camera can capture. In the case you described, there are physical limits. If you exceed that, your SOL without combining multiple exposures. So you could use a medium format digital which is better at grabbing more light than small format digital or use medium or large format film and use the zone system to compress the high values and bring in more "stops of light".
