I'm afraid it's a stupid idea, because it won't work. :-)

The reason is that the process is not running as root or the exim user
at this point. Therefore, it cannot write to the log file.

Actually, that is not quite true. If the log file has been previously
opened, then it will be able to write to it, but you can't rely on the
log file being open.
