Get the Five bumper skin so you can get integrated fog lights. If it's doable, too bad the 2012 no longer has Intelligent Park Assist as they won't have the holes for me to retrofit my sensors.
My lovely wife has a habit of knocking into things with the right front corner of the Prius! I'll be looking for a new bumper skin as soon as we buy an old clunker that she can dent without any concern.
