Whenever you update Mordekaiser, what would you do to give him new visuals?

It's pretty obvious that Mordekaiser is one of the "bad apples" of visuals in League, to say nothing of his gameplay. Siphon of Destruction doesn't have a real visual for the cone, just the hit, and when his enslaved ghost from Children of the Grave dies, it just vanishes with no animation whatsoever. That and his cast animations (besides his Q) all look the same: he just sticks his hand out and bellows.

Pretty boring.

Seeing as Meddler is looking into updating Mordekaiser due to DFG's removal, I was hoping that said gameplay rework could be accompanied by a visual update. This seems unlikely right now, but one can hope, right?

If such a visual update is being looked at, how would you be altering our big metal man? What other motifs would you take from? Arthas (the Lich King)? Ganondorf? Monty Python?
