It is trivial to get the script working. In fact I got to trim the bulk that provides Internet Explorer compatibility. The only tricky thing is variable scoping for a running GreaseMonkey user script.
It is working well for now. You can download the user script from the GreaseMonkey section. It is not as configurable a the regular Scripturizer for JS, i.e. you cannot re-configure the engine by changing variables/parameters at runtime. However, it saves you a click to "scripturize" the HTML document, which currently can be done using the bookmarklet.
