Hello,

I don't have good elisp skills, but the following might give you an idea
how to start:

(defun org-todo-recursive (element-at-point)
  (interactive
    (let (element-at-point)
      (forward-char) ;to make sure you have item (no
plain-list)

      (setq element-at-point (org-element-at-point))
      (list element-at-point)))

  (if (eq 'headline (org-element-type element-at-point))
      (progn    ;
then

        (narrow-to-region
         (org-element-property ':begin element-at-point)
         (org-element-property ':end elemen-at-point))
        (setq headline-content-list
              (cdr (car (org-element-contents
                    (org-element-parse-buffer)))))
        ;; Need to use cdr, as first thing in list is a plist with
properties
        ;; Need to use car, as 'contents' is between an extra pair of
brackets
        ;; Now you got a list with org-elements of
form

        ;; ((section (...))(headline (...))(headline
(...)))

        ;; Perhaps run over them in a while loop, if type is headline, then
(org-element-put-property current ':todo-keyword ...)
        (while (not (eq <lenghth of list> 0))
          ((setq current (car (headline-content-list)))
           (setq headline-content-list (cdr (headline-content-list)))
           (if (eq 'headline (org-element-type current))
               (let ((todo-keyword (org-element-property
                                    ':todo-keyword current)))
                 (<Change the property depending on current state>)
        )
      (message "Must be on heading")) ;else


Have fun,
Dieter
