I think you've something bigger here than you realize. :-) If you would indeed: 1) introduce some opportunity for others to write stylesheets; 2) support custom domains, then I would expect something like this to really take off. I see many advantages: Not all kind of Wordpress plugins that have to be checked or maintained. Not explaining what can be adjusted, what not. Having a very simple user interface for people (Google docs) that just works. I foresee also some disadvantages, especially about customization: from SEO, to footers, contact page, etc.
