For logging, could you just take one of the audit modules, change the
syslog facility and redirect that facility using syslog.conf?

You want to make your rmdir and mkdir operations opaque because you are
providing an alternative implementation of the operation. If you made
them transparent and another module came along with it's own opaque
implementation, what would happen?
I would definitely separate your directory modifications into a
different module from your logging one.
