What does it even mean to re-embrace it? It was never mainstream in the USA, and even Mormons made that practice illegal before Utah became part of the USA.
Are you talking about turning yourself into the new Joseph Smith, Jim Jones or David Koresh?
Otherwise, people, in the USA, Western Europe and other parts of Europe, are free to do whatever they want. Legally, you don't need to be married to enjoy the protections afforded by law (inheritance, etc).
So, there's really no need to re-embrace anything at all. Check out what Elon Musk is doing now: he built a compound near Austin, Texas where all his concubines and baby mommas, along with their offspring live. If anyone in his Harem has a complaint, they take it to civil court.
You can't afford it, try (or maybe that's what you're doing) starting a movement on SW (like some do), looking for vulnerable women to join. There's still the question of who pays for what, but maybe you have a bottomless checking account... 🤣
