Cho'gath ultimate skin

I would like to maybe introduce the cause I'm still working on the skin but I think it could be amazing to create or maybe give an idea for this champion. I have Battlecast Cho'gath but I was wondering something more exceptional like Dragon Cho'gath with an amor. I was thinking for is Q to maybe do normal earthquake with fire all over the other champion but as a stun, doesn't mean the champion need to burn. The W as silence, I'm not to sure about the idea, cause i need help from others summoners to give maybe an idea about the project. The E, cause is an automatic program could be throwing fire all the time cause like a Dragon ( if any other suggestion i can rectify the E) . For the last part, the R could be developing is Wings and make him also big. Therefore when he didn't eat another summoner champion, he stays as a baby dragon. The he can get a little bigger, for the second when he eat a minions or a champion he can develop is wings and his size. But his wings need to be full up to lv 6 but eating to make him fly around the map as he was walking but except is flying . I think for the name it can be discuss I was thinking to give Eragon Cho'gath but give your comment if you disagree or you want give an idea :)
