bulk invite GitHub watchers and stargazers

I have an open source project with several watchers and stargazers. Many of them have been interested to join the Gitter chat for my project, but the Gitter badge in my README wasn't a sufficient way to get them to join; it took manually inviting them from Gitter's "add people to this room" UI. Would it be worth adding a button to Gitter to bulk invite all the watchers and stargazers of a project, so interested followers could be invited easily, rather than one-by-one?

Thanks for your consideration, and thanks for Gitter!
