I Wonder, What if John Cena won The World Champion Against Gunther at WM41?

Imagine the storyline now, would Cody walk out of Mania as champion? Would he turn heel? Would he have fought someone else like Punk? Rock? Orton?

I feel like now it would've been pretty cool to see Cena have a rivalry with Gunther, it would elevate Gunther as an even more of a threat and he could've elevated his promo skills to the next level
