I think this ultimately misses the point because it doesn't understand what "Mainline" means. It's not a marker of theological centrism, nor of a "higher" Protestantism. Mainline is a social class marker. Mainline churches are those which are populated by the bourgeoisie and the "respectable" classes of society. There is almost no real theological content to "Mainline" identity. In the book, Vanishing Boundaries: The Religion of Mainline Protestant Baby Boomers, Hoge, Johnson, and Luidens survey the characteristics of the decaying Mainline denominations in the latter half of the 20th Century, the authors find that being Mainline was primarily an identity grounded in social and class factors, but that nearly none of their subjects identified with their denomination on the basis of theology. Episcopalians, Methodists, Presbyterians, Congregationalists, ELCA, Northern Baptists, various CoC denominations, all repeated the same results on their surveys: they did not consider theological differences to be salient between Mainline groups and scored extremely high on measures of Universalism. They identified themselves as distinct from Catholics and Evangelicals, but considered all Mainline churches essentially interchangeable. Hoge, Johnson, and Luidens find that the main causes for conversion between the various denominations are personal convenience issues like marriage to a different Mainline Protestant or driving distance to a nearer church. Mainliners who moved away from their hometown were among the most likely to convert to another Mainline denomination.

Revival of Mainline Protestantism in any form is destined to fail because being Mainline is about being the default beliefs of the respectable class of upper-middle class folks. Where did the converts come from who constituted the Mainline boom in the 1950's? As Robert Putnam and David Campbell tells us, it came from the rising income of working-class Evangelicals and Catholics. They use a clever analogy: just like these rising middle-class folks traded in their Chevy for an Oldsmobile, they also traded in their Evangelical or Catholic faith for Mainline Protestantism. It was the class, not the theology, that defined the religious identity marker of "Mainline."

Today, what is the default religion of the respectable upper-middle class? It's not going to be any kind of Reformed Christianity, for sure. Theologically serious Christianity is the most absolutely low-class thing you can espouse among our Managerial Upper-Middle Class. As I've said quite a few times, I'm of the opinion that Mainline Protestantism is alive and well in America today as the current religion of respectable Upper-Middle class folks. It's dropped its pretensions at being a theological faith, and dropped the unnecessary elements of Sunday worship and maintaining a sanctuary. But the social theology of respectable, upper-middle class religion is alive and well in the secularized jargon of mainstream center-left culture. It's no coincidence at all that the most prominent political theorist of the UMC, John Rawls, started his career studying theology.

The existence of the Mainline was a product itself of the Positive World. It was a result of the fact that those denominations were Respectable, in contrast to the working-class reputation of Evangelicism and Catholicism. There really is no such thing as a distinctive Mainline theology waiting to be restored, as well-groomed professionals with Ivy diplomas crowd the doors waiting to return to their grandparents' churches. My suspicion is that people who bemoan the collapse of Mainline denominations are doing so less because they miss the distinctive Episcopal doctrine of the Three-Legged Stool or the modernized liturgy of the 1979 Book of Common Prayer, and more because they don't want to be associated with dirty, white-trash, pickup-driving, ignorant fundies like me.

I think it is going to be tough to rebuild any version of a Mainline if it is at all tied to denominations. Ryan Burge's studies suggest that the two trends are Nones and Nons. Within Christianity the trend is going to continue to move towards non-denominational churches due to all institutions being discredited--and non-denominationalism sort of prevents a new Mainline from emerging because it would necessitate some kind of shared values and centralized structures.
