The theocracy is neither Sunni nor Shiite. If you are an educated Muslim elite you can gain power.
I'm pretty sure that while a regular Muslim country might be able to create unity or at least grudging peace between Sunni's and Shiites, a Caliphate like you said we are wouldn't. One of the main reasons of the Sunni-Shiite Schism was from how to choose the next Caliph thus you are either Sunni or Shia as a Caliph. You can't be both.
