Playing that from day 1 wouldn't work, I think. Connecting to the other players in a realistic fashion would be pretty much impossible, and you'd be too much of a loose cannon to work with anyway. Plus you'd probably be too busy, you know, surviving.
Playing such a character a few months in (so, once you've been able to settle down, meet the other players so you have a reason to be seen with them) would probably work, I think. In the right group.
