Lane here. I would love to see this as well. Anecdotally, most the Mormons I know in Utah leave for atheism/agnosticism, especially if they're a millennial like me.
However, the Latinos I know tend to leave for some form of non-denominational Christianity or vague theism. The reasoning I get from my Latin friends is that "it's crazy to not believe in God at all". I'm thinking it has to do with how few atheists there are in their communities.
