If not the iron cage, then basically I am suggesting an application of the ideas in Weber's Protestant Ethic for battling Islamist extremism. My reasoning goes like this. Since any theocratic system, in order to exist, must have convenience for a politico-economic system, then the more specialization that occurs on the theological side of the house, the more bureaucratization, and hence more modernity, occurs on the politico-economic side of the house. This should explain or expand on what I suggested. In practical terms, it means encouragement of sectarianism, as well as other forms of specialization, rather than discouragement of theological differences. The resultant tendency of the spiritual mind to "exhaust" itself, so to speak, while trying to comprehend all the theological specialties would force a "practical" turn toward secularism. I'm just applying Weber as I understand that kind of sociology.
