Maybe just add the wanted face as 'persistent-face, remove 'fontified and then use a function like above? (But I am not sure how to "refontify". Is not turning font-lock-mode off/on a bit heavy? Though that new font-lock-fontify-region-function could be called directly of course. With some twistes then to avoid making the buffer modified.) A problem with this solution is however that fontification must use font-lock-fontify-region-function etc. All major modes does not do that.
