It would have to be done each time Org is loaded.  Unfortunately Emacs
doesn't provide an interface for removing such definitions, so you'd
have to traverse a number of not-too-well documented data structures to
get rid of them.  I'm still not sure I found all of these nor if there
are adverse effects of doing that.  Eric Frage (IIRC) was testing a
rough version of what I was trying to do, he reported he was seeing
problems that he wanted to investigate further.  Now, with the dust from
all the other changes settling, we might pick up where we left before:

--8<---------------cut here---------------start------------->8---
;;
;; Kill our ancestors
;;

;; clean load-path
(setq load-path
      (delq nil (mapcar
		 (function (lambda (p)
			     (unless (string-match "lisp/org$" p)
			       p))
			   load-path)))
;; remove property list to defeat cus-load and remove autoloads
(mapatoms (function  (lambda (s)
		       (let ((sn (symbol-name s)))
			 (when (string-match "^\\(org\\|ob\\|ox\\)-?" sn)
			   (setplist s nil)
			   (when (autoloadp s)
			     (unintern s)))))))
(add-to-list 'load-path "/path/to/org")
(load "org-loaddefs.el" nil nil 'nosuffix)
--8<---------------cut here---------------end--------------->8---

This assumes it is run before any Org functions have been used and makes
no attempt to check if that's true.  Another unverified assumption is
that nothing has polluted the namespaces that Org uses.

Achim.
