I do not know the usual way.  

Have started with the following but with few ideas of how to supply appropriate value to buffer.

(defun mode-sweep (mode)
  "Cycle the buffer through three major modes (text, org, normal)."

  (interactive
   (list
    (let ( (cseq '("org-mode" "text-mode" "normal-mode")) )
      (completing-read "Major-mode: " cseq nil t "normal-mode"))))

  (with-current-buffer buffer
   (funcall (intern mode))) )
