Global Site Tags Plugin with WP-Cumulus

WP-Cumulus is an awesome plugin that shows your tags in a 3D tag cloud. My question is, since I can't find support for MU with WP-Cumulus, I was wondering if there was a way to cross breed Global Site Tags and this WP-Cumulus plugin to show a 3D tag cloud of all global site tags on my WPMU install... any help? Suggestions?
