The correct way to encode these images would be to scale the samples up to 16 bits or to encode the image using 14 physical bits. The latter approach, however, probably isn't compatible with any existing software.
There is existing software which can handle 14 bits. I notice that 12 bit TIFF is in use to capture the output of scientific/industrial CCD sensors. 14 bits is only two more bits than 12 bits, and is therefore completely achievable. :-)
