War Machine Sion

Since Sion is now this big gigantic juggernaut from the dead, I wonder if Sion could be changed into the giant mechanical war machine where you would see explosions from Sion's shield or a nuclear bomb axe from that fully charged swing, or how his growl attack would be this cannon he shoots from his mouth. But for his unstoppable onslaught, I'd say he would have a booster on the back of him similar to the mecha malphite design. The booster gets greater, the war machine gets hotter, and upon impact or at least at the end of distance, Sion would make a nuclear explosion! For his passive? The system overloads and Sion loses control. After his life energy goes down, he self destructs. Plus, he would have a mechanical voice.

So what do you guys think? Is Hex Tech Sion good enough or do you want Rito to give this skin idea a shot?
