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.
