No the older Birger mount will not work on the Epic. The two cameras have entirely different mounting engineering. Your only other option is to look at a "dumb" non-electronic option that will go into the PL mount. This is not ideal, and I don't think that I would recommend it as the aperture will always be wide open on the dumb mount.
Really the best bet right now is the Red Canon mount for Epic. I saw that a Leica mount is also available from a third party for the Epic, but I don't think that helps you.
