Looking For Achievement Add-on

I looking for a way to add a special set of icons/medals/ribbons under a users avatar or name, perhaps a special addon. We already have the trophy system but I want to make it so I can add special achievements under a users name that they can not edit. I was even looking into perhaps a secondary signature box that they can not edit. Any ideas? If you want to see what I mean I can upload a photoshopped image of what My vision would be.

Thank You for your time
