I'm not spotting any hook that could be used for this. The <<<target>>> fontification happens through a simple 'regular expression => face' mapping in org-font-lock-keywords. You're probably aware of this and it's just not as automatic as you'd like, but just in case: pressing `C-c C-c' with point on <<<target>> will call org-update-radio-target-regexp.
