New Galio Skin Ideas

Now that Demacia's old stone guardian has upgraded from Sentinel to Colossus, let's think of some new skins that will work for him. Also in case a Rioter sees this and feels like chiming in I do have a question for you. Since Galio technically already has a robotic skin in the form of his Hextech one, would giving him a Mecha skin or something similar overlap the theme and thus make that idea not really plausible?

As for my idea, how about something like Elderwood? Instead of a stone and metal construct he will be more of a tree/rock construct.
