Aliasing a DOM function (Document.Write) and scripts on other domains

Question

I want to force external 3rd party scripts (on seperate domains) to use my own custom implementation of document.write when I load them on my domain.

ie:

document.write = function(args) {
    // My custom Function
    }

This works fine for scripts on the same domain, but scripts on other domains use the browser default. Can I override this?

Here you are:

(window.HTMLDocument ? HTMLDocument.prototype : document).write = function(s) {
    this.title = s;
}

Both in IE and in non-IE, "this" object is the browser document object.
