Great points on both accounts.
The issue I think will on its own eventually make it to the highest level courts. Not that Christians should try and push for that because they should not (see 1 Cor. 6). We do not need the weapons of the sword to promote any Christian faith view but would only like to have the sword to protect people of faith views as they share their faith.
But several legal scholars have said that the anti-polygyny laws would probably not hold up in the court of law today if it were reviewed. The earlier laws against polygyny were basically aimed to suppress a religion by another religion that did not like the religion that supported multiple wives for men. Thus, the actual case law and legislative laws themselves were based on unconstitutional grounds, or at least it seems.
Legal scholar Stephanie Forbes wrote a good article about this. It can be accessed here.

Her final view was that legally there remains no justifiable reason as to why marriage should be defined as some traditionalists have. I'll quote her conclusion here below (but I urge people in general to read the whole aritcle as it is very helpful).

Stephanie Forbes: Why Just Have One?
The purpose of the American Revolution was to gain freedom
from English control and the tenets of the Church of England.
The colonists did not want to have an official religion and wanted
religion and government to be entirely separate. However, the
existing anti-polygamy laws are an example of a departure from
this proposition.The Mormon people were clearly coerced by the U.S.
Government to abandon one of their religious beliefs—
polygamy.The legislators responsible for passing anti-polygamy
legislation clearly felt threatened by the Mormon
Church and were vehemently opposed to the practice of
polygamy.This legislation would not survive a modern day
Establishment Clause analysis. In effect, such legislation is
“[o]fficial action that targets religious conduct for distinctive
treatment.”The decision reached by the Supreme Court in Church of the
Lukumi Babalu Aye, Inc. v. City of Hialeah is particularly
instructive for determining whether a statute is neutral on its
face or in its application.The anti-polygamy laws, when
evaluated under the same analysis used in Lukumi, are clearly
not neutral and were passed directly in response to the Mormon
Church’s public announcement of its intent to practice
polygamy.The U.S. Government interfered with the Mormon
Church by passing numerous anti-polygamy laws, none of which had a secular purpose. The comments by the legislators duringthe congressional debates evidenced their preference for
Christianity over the Mormon faith. This is the exact type of
legislative action that led the Court in Lukumi to strike down the
ordinances as non-neutral and therefore unconstitutional. It is evident from the discussion above that if a religiously motivated law has lost much of its religious “flavor” over time
and has evolved to have a secular purpose, it will survive a
constitutional challenge.However, unlike the Sunday closing
laws, the anti-polygamy laws have yet to experience such an
evolution.Polygamists are not harming society and are trying to live
their lives according to their religious beliefs. While there are
abuses that occur in polygamous relationships, those same
abuses occur in monogamous relationships as well.
There are bad seeds in every aspect of American society, and an entire
religious belief should not be suppressed simply because of a few
bad actors. Mainstream society has recently begun to respect many
unorthodox and alternative lifestyles. Some states have extended
legal rights to homosexuals, unmarried cohabitants, and single
mothers. The line between acceptable and unacceptable
behavior is incredibly blurred. If the anti-polygamy laws are
upheld, the government should be prepared to review the legality
of other alternative lifestyles. There is no secular purpose for
continuing to outlaw polygamy. The United States was founded
on religious freedom and the freedom from interference with
religion. Polygamists should finally be able to fully realize this
freedom.
