Not all input methods are bijections. Especially not many of the Asian
input methods.

Really? Try typing the following using the ipa input method:
tsh1tsh2tsh3
The number selects the specific form. If something else it typed rather
than the number, it will use the last remembered version, defaulting to
version 1.
I hacked up the following, which is minimally tested, but may work for
you. I tried to use public functions from quail, but the (null (cdr
map)) is probably an implementation detail, and might break in a future
version. There are almost certainly better ways to write this function.
If presented with an ambiguity (like above), it will choose the last
remembered variant (defaulting to 1).
(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 ""))
(while (< idx size)
(let* ((next-cand (concat cand (list (aref data idx))))
(map (quail-lookup-key next-cand))
(def (and map (quail-map-definition map))))
(if (null map)
(progn
(insert next-cand)
(setq cand ""))
(if (and def (null (cdr map)))
(progn
(insert (quail-get-current-str (length next-cand) def))
(setq cand ""))
(setq cand next-cand)))
(incf idx)))
(insert cand))))
