Lesnar attacks and "injures" Christian between now and EC taking his spot in the chamber... he gets eliminated via rollup and goes crazy beating down anybody still in the ring at the time and walking out.... Undertaker appears on RAW the night after EC and calls out Lesnar... Lesnar gets in the ring and Undertaker says "You're in my yard now!" and proceeds to beat him down setting up a feud and WM30 match between Lesnar and Undertaker. Daniel Bryan wins the EC match leading to a triple threat match for the title at WM30. Bryan vs Batista vs Orton
While I would have no objection to Lesnar taking out Christian (especially given the promo Christian cut about the "window closing" on his opportunities) and taking his spot in the Chamber and getting eliminated before beating the hell out of everybody and leaving, I don't see Undertaker calling anybody out, not to mention that Taker yelling "You're in my yard now!" in 2014 would just be narmy as hell. But, there are ways for Lesnar to turn his attention to Taker after EC and end up facing Taker at Mania that would seem more natural.
As to the idea of Bryan taking the title at EC and getting added to the Title match at Mania, I fully support it.
