This is not a good strategy; it's not working in the github.io versions (presumably because of cross-domain security restrictions), won't work in w3.org either without manual editing, and is kinda clunky. I've brainstormed a few ways to address this, each with pros and cons:

FWIW: I had such a script for the CSVW Working group:

https://github.com/w3c/csvw/blob/gh-pages/replace-ed-uris.js <https://github.com/w3c/csvw/blob/gh-pages/replace-ed-uris.js>

although that WG used one repo for several documents, we had a similar problem. I think the same script would work over several repos; it just uses a separate js file that lists the document URI-s themselves. There is a short documentation at the start of the script.
