Not overkill at all. You should teach your friend a lesson and set up another friend to sneak up to his bike while you guys are inside somewhere and hide his wheels from him. Teach him a lesson in good humor lol. It only take a few seconds to get two quick release wheels off a bike so your just protecting your property. If you really want to protect your wheels still but dont want to keep going through the "hassle" then consider some skewer locks so they are already attatched.
