Not possible, and probably ASB.
There is not monolithic "fundamentalist" movement in the United States. What left wingers call "fundies" encompasses a broad range of church organizations, The Southern Baptist Convention, The Assemblies of God, numerous smaller organizations, plus thousands of independent church congregations. While in broad agreement on matters of faith and morals these churches have many differences in Biblical interpretation. On certain issues they are disdainful of each other. (Ask a Baptist preacher what he thinks about "speaking in tongues" in a Pentecostal service, for example.)
These groups, and their memberships, tend to be suspicious of centralized authority and governmental power. They have roots in the Protestant reformation and are opposed to anything that, in their view, would stand between the believer and God. They are also highly democratic, in that all decisions about church governance are made by the local church, in the form of the congregation, by vote of the membership, not a far away official.
It is not fertile ground for a movement for a top down dictatorship.
The whole reason that the "religious right" emerged in the 1970's was as a backlash against against what they viewed as a society that had become overly permissive and hostile to them. They did not want to impose a theocracy, but to prevent the imposition of a secularized state, implicitly hostile to Christianity, that would impose an alternate morality in place of traditional morality.
