Raw/Elimination Chamber - Smackdown/???

[SuperSlim]

I've just been thinking and realized that Raw really does have their own specialty match. Every chamber match has been a Raw only Chamber. The chamber has established that Raw label on it and except for the last one the others have been pretty good.

Looking at Smackdown! they have nothing to call their own. They don't have a specialty match just for SMackDown! like they do for Raw. So my question would be what sort of match could be created just for SmackDown! since Raw has the chamber?
