To me kon needs to feel a dm act like a 18 to 21 yr old, live in Hawaii, work for Cadmus, go on covert ops when he isn't with his YJ4 crew, and wear either YJ shows season 2 or 3 clothes, superman "Truth" blue shirt, but always have the black and red S on the chest, fingerless gloves, and a leather jacket around, power wise YJ show powers with a mix of kesel and new 52 TTK, keep it tactile and make it work with his focus, but give him plenty of power with it.
I like most of all your ideas guys, just let's remember let's stay true to the character as seen in the past in every variation, and he isn't the heir apparent so he needs his own thing, and shouldn't be "competition" for Clark
