While the idea is sound, I doubt it will happen. WrestleMania XXX is looking to be the biggest of all time, and while Antonio Cesaro swinging Big Show would be a huge WrestleMania moment, it isn't big enough. Or it shouldn't be. Having said all this, WWE could decide for it if nothing else can work out.
Regardless, I'd like to see it. The big swing on the Big Show? Yes please. Antonio Cesaro deserves a break. Get the WWE Tag Team Championships on the Real Americans, push Cesaro, and build your next big star. All he needs is this moment you have suggested.
