Yup.  This version seems to do the trick, though:

(defun accentuate-region (start end)
  "Replace the region by using it as keys using the current input method"
  (interactive "r")
  (save-excursion
    (goto-char start)
    (let* ((data (delete-and-extract-region start end))
           (size (length data))
           (idx 0) (cand "") map def)
      (while (< idx size)
        (let* ((candx (concat cand (list (aref data idx))))
               (mapx (quail-lookup-key candx))
               (defx (and mapx (quail-map-definition mapx))))
          (if (null mapx)
              (if def
                  (progn
                    (insert (quail-get-current-str (length cand) def))
                    (setq cand "" map nil def nil)
                    (decf idx))
                (insert candx)
                (setq cand "" map nil def nil))
            (if (and defx (null (cdr mapx)))
                (progn
                  (insert (quail-get-current-str (length candx) defx))
                  (setq cand "" map nil def nil))
              (setq cand candx map mapx def defx)))
          (incf idx)))
      (if def
          (insert (quail-get-current-str (length cand) def))
        (insert cand)))))

I'll work on the inverse function in a bit.
