What is your ideal demographic coalition?

All Protestant, all the time.

Would you let Brian McLaren into your coalition before Peter Kreeft?

Almost certainly no, upon a Google search of the two.  I was being a bit tongue-in-cheek when I implied only Protestants would be included, as I'd imagine my positions would be attractive to a lot of conservative Catholics, especially as I am more economically centrist than the median Republican.

Almost certainly, yes, upon a Google search of the two.

Really? Huh.

Whoops, I meant to say no, as I think is clear from my statement thereafter.  McLaren seems awful.

As for the OP,

Take the current GOP coalition. Kick out the lame mainline Protestants. Nathan doesn't count here. I'm talking about the fiscally conservative, socially liberal, Mom wants the kids baptized at St. Michael's Episcopal Church, mainliners. Add religious Hispanics, both Catholic and Protestant, as well as middle class, religious blacks.

RINO Tom cries.  Sounds like a good coalition to me though.

The vast majority of Nonreligious people, members of the working class that aren't strongly religious, (and this is where it gets interesting), the highly intelligent (especially the young ones , even more so the ones that rebel against some of society's bullsh**t\ don't conform), nonconformists in general,

scientists, the more liberal side of the tech industry(e.g. Larry page, Sergey Brin, not apple, and not Zuckerberg ), socially very left-wing suburbanites that aren't rich enough to vote for people who would criminalize things like being gay, being an independent woman, being an effeminate guy,  or using hair dye if they promised to cut taxes,

 feminists, BLM, polyamory supporters, members of the LGBTQ+ community (especially the TQ+ part), small farmers struggling against giant companies (esp. ones who practice humane/sustainable farming practices),

green energy companies, the portion of the rich who realize that they've been given an unfair advantage in life and want to change the system, people who have to live off welfare because there are no jobs they can do, young liberals, likely the children of millenials, Palestine activists, small artists, and people living in dense cities.

I would have strong opposition from catholics, mormons, upper-middle class people, exurbanites, the majority of the rich  (the bastards who fight to be able to screw everyone else over to make more money, give nothing to the needy, and buy private jets and such), evangelicals, people who strongly value conformity(they do exist, though they aren't as common as they once were), highly religious people in general,

 Israel hawks, neocons, Internet service providers and the corporate side of the tech industry(I support banning ad tracking software and staunchly oppose measures to end net neutrality), health insurance companies, for profit prisons, big farming corporations, the rich and powerful in general, idiotic "news" sites like breitbart, salon, fox, and MSNBC that do nothing but feed their readers biases and make them worse, and the alt-right.

Are we really that uncommon?  People who are repulsed by edgy-ness and things like blue hair, nose piercings, and the like?

My coalition is easy.  I want everyone to share my values.  My Republican Party would probably do better than the current Republican Party with Hispanics and some blacks due to a strong focus on the family more than on stuff like immigration.  We would still do pretty well with the rich due to a near abolition of taxation, but we would probably suffer with secular working-class whites, as protectionism would be a non-starter.  But, it wouldn't be too far off the June 15, 2015 GOP coalition (the day before Trump announced his candidacy).

The two bolded things don't go together, I'm afraid.  There's a reason that even socially conservative blacks and Hispanics weren't raving for Rubio, Cruz, Rand, etc., and a further-right approach on fiscal policy would only compound the problem, unfortunately.
