No.

The session being deleted does NOT mean the user has left. And the
user may leave WITHOUT closing the browser window (he may type in
a URL, click on a bookmark, etc.) Unless the user is highly motivated
to explicitly log out (like the site contains private info or can
be used to spend real money), the vast majority of logouts are going
to be by timeout.

You also don't get to run code when the session data is about to
be deleted.
