Chrome Extension - Gmail Batch Reply

I often wish Gmail allowed me to select these messages then click a "batch reply" button, which would allow me to send the same reply to each of the individual emails without having to open each of them and enter the canned response. I am looking for someone to write a google chrome extension to allow myself (and other users who wish to install it) to select multiple gmail conversations then click a "batch reply" button. A new compose window would then appear populated with these email addresses.
