You "just" need to inject your own Javascript code into the fetched URL, and in that Javascript code redefine window.alert() to be the function you want.

If you're not tied to using Internet Explorer, you can easily do that with WWW::Mechanize::FireFox, but I'm biased, because I'm the author of that module :).
