I suppose you'd want to be careful about increasing the gain very much because I would expect you could lose dynamic range quickly or increase noise just like higher ISO's do.
ISO is a bit misleading in that you've got to capture the signal before you can amplify it. As I recall from school, 10 times zero is still zero!
