Lawyering for the lord.
You know what would save the mormon church....Really. Just come out and say "Look Joe Smith and Brigham Young taught a lot of false doctrine, but we're good people and want to convert the church to christianity". We'd accept that....There are a lot of GOOD MORMONS out there.
When you hold to the false doctrines AND claim to be Christians is when the fist approaches our face. You will not infiltrate and corrupt without a fight.
Consider my post #1536 a response to you, too.
They could always go back to the tactic they used when I was a small Mormon girl and proudly told people, “I’m not a Christian, I am a MORMON.”
I see it totally possible in a century that they will be discussing their Trinitarian philosophy and love of God's redeeming grace, works will fall into their true place in God's plan and the whole Nephi/Laminate bit will turn out to simply be a parable to teach his people.
