You would be better off just adding an external RTC. There are capes available that add a RTC. Any battery that was adequate to keep the board up for shutdown would be more than a typical RTC would require. The isn't enough space on the board to add a rechargeable battery that large.
I have no plans to make these changes, but thanks for the input.
