Have you tried using the CANVAS shellcode generator? I know you can
add "bad characters" to your exploit and then it will generate the
shellcode, excluding the characters you specified.

Every character left out however, will grow the size of the shellcode.
leaving out that many characters could make your shellcode too large,
but its worth a shot
