Nick,
That does sound like a fun way to take advantage of the differentials in the kilns temperature and atmosphere based on placement, and with a natural clay to, that is exciting!
Wood firings are quite the process, I recall workshifts of chopping wood, followed by late nights of stoking and then back to more chopping! Some of the anagamas are very ingeniously designed, using heats desire to rise as a means of continuing a massive firing. Some I've heard can reach cone 14! I'm hoping to get involved in another wood firing soon.
