I hope it works and wish for the best. Escaping the Walled Garden of Facebook is tricky business. You may need to keep a strong presence on FB as, "People go where the people are." An interface (app) keeping the connection open would be good. Breaking free is tricky but possible. The most enormous of efforts can get you a 1% interest and a 0.1% dedication, which should be enough to sustain your project as it grows. Also, utilize existing systems. Think of it as "sinking your spider legs" in. One spider leg stays in FB, another spider leg on youtube, another spiderleg on google+... and have a spider leg in as many existing social networks as possible. This will support the body of your website.
