I don't feel the need for a plan to rotate batteries. The camera can tell you not only the charge status of a battery, but its condition as well. If a battery starts to show deterioration, I will replace it. I have employed two D700 bodies and a total of six batteries for more than four years and none of them have failed nor are any in need of being replaced even now.
Based on my experience with the D700 cameras, I will probably limit my battery "herd" for my two D800 bodies, to a total of four. Six was obviously overkill for the pair of D700 cameras. (I want to use the plural of D700 as D700s, but then I am often asked where I got that model!) If I am travelling more than overnight, I take a charger with me, just in case. They are small and light.
