I tend to expect that nobody has, since no version of UNIX I know of
keeps track of the number of failed login attempts made on an account. 
You'd have to replace "login" in order to do that; I seem to remember
somebody doing a publicly-available reimplementation of "login", but I
don't know whether it can replace the versions of "login" on all the
systems you mention or, say, just the ones on systems with S5-based
implementations of "login".
