It's entirely feasible. I even have an outline written up:

Maybe if I have time left after category sorting this summer, Wikimedia could have me do this.
Note that, as Aryeh's proposal mentions, it'll have to rely on JavaScript in order to not totally kill our caching infrastructure. This means censoring will not work for users who have JavaScript disabled or use JavaScript-incapable browsers.
