There is no way to do this easily right now.
However, this command will display the remaining effort:
#+begin_src emacs-lisp
(defun my-org-display-remaining-effort ()
"Compute remaining effort for current subtree."
(interactive)
(let ((clocksum (org-clock-sum-current-item))
(effort (org-duration-string-to-minutes
(org-entry-get (point) "Effort"))))
(message (org-minutes-to-hh:mm-string (- effort clocksum)))))
#+end_src
Also, the attached patch allow to postprocess property values with
custom functions when inserting them with org-set-properties.
Let me know if you find this useful!
Best,

Subject: [PATCH] New option `org-properties-postprocess-alist'.
* org.el (org-properties-postprocess-alist): New option to
allow postprocessing the values of properties set through
`org-set-property'.
(org-set-property): Use this option.
This is inspired by a request from Pascal Mattia.
