     I did this once.  I knew what my passphrase was supposed to be,
so I wrote a perl script to generate as many typo-like variations of
this as possible, and then I tried pgp (was still using pgp at the
time) with the -z option.
     With gpg, it would look some thing like (zsh syntax)

for i in $(cat passphrases.txt)
do
  echo $i | gpg --passphrase-fd 0 --decrypt filename.gpg
done

     With a little luck and a lot of time, you might end up with your file.
I had to do this twice, and I was only successful once.
