You really couldn't do this. If WWE had any logic, they'd realise promoting their most over guy to possibly fight two matches absolutely must fight two matches. Simple as. The Royal Rumble was a major failure critically, and I don't think they'd want to do the same at WrestleMania XXX, arguably their biggest event in history.
The thing is, if it wasn't Randy Orton (c) vs. Batista for the WWE World Heavyweight Championship, it could be possible for Daniel Bryan not to defeat Triple H. But, this feud needs life injected into it, and the match will be a flop without that third man. Plus also, if Daniel Bryan defeats the thirteen-time world champion in Triple H, then wins his fourth world championship in the main event against Randy Orton and Batista at a WrestleMania, this would be a huge boost in his career. WWE simply cannot miss this opportunity.
