I figure there's two good ways to get there from EC onwards.
One is simply to do the correct match to do at 33, a year too late. With Bayley's win on Raw, I would have Bayley quickly eliminate Alexa in a surprise, have a quick stalemate, fine match with Sasha before the ring fills, Sasha gets 2-3 eliminations clean, then grabs a pair of brass knux (which Sonya took to the ring with her and got superkicked off by Mickie), Sasha would punch Bayley's lights out to win the belt. Heel it up gradually, talk shit week 1, come out with bling and cars week 5, etc on the way there and trust Ryan Ward to work his magic with Bayley again.
The more realistic option is this mini-angle of how Alexa is trying to befriend the people in the Elimination Chamber as the female Miz, and trying to get an alliance formed quickly... Well she can start last, sneak an EC victory, then later on in the night she can run in and totally fuck over Nia Jax in her match with Asuka... Next night on Raw Asuka pseudo-turns heel by shaking her hand, thanking her for the opportunity, and going after the Smackdown championship and having a big old celebration as... Nia's terrible music hits, Asuka bails as Alexa is trapped in the ring and Nia starts to really punish Bliss. Beat her down before a quick backdoor escape leads you wanting more...
Oh and fuck Ronda.
