Being a big-time M*A*S*H fan, I think Hawkeye is awesome. I see no reason why you can't use it as a first name if that's what you want. I know a boy named Hawk and it fits him well. Personally, I like Hawkeye better.

On a side note, I have an unusual fn and a common middle name and I love my name. If, for some reason, I really didn't like my fn I could easily go by my middle name. I tend to choose unusual fns with more "normal" mns for that reason.
