Something like this perhaps:
(defun rotate-window-buffers()
(interactive)
(let* ((windows (window-list))
(buffers (mapcar (lambda(w)
(window-buffer w))
windows))
(wpoints (mapcar (lambda(w)
(window-point w))
windows))
(w (pop windows))
)
(setq windows (reverse windows))
(push w windows)
(setq windows (reverse windows))
(mapc (lambda(w)
(let ((b (pop buffers))
(p (pop wpoints)))
(set-window-buffer w b)
(set-window-point w p)))
windows)))
