Interesting concept.
I do think it might have the effect of forcing Republicans to spent a lot of time in Utah trying to make Mormons happy rather than spending a lot of time in Iowa and South Carolina trying to make evangelicals happy.
I'm not sure that would be a helpful outcome.
It isn't intended as Mormon-bashing to point out that Utah is one of the most strongly Republican states. A lot of the states which are very red or very blue are also very small, and scheduling early primaries/caucuses in those states might result in major influence by states which are not in any way reflective of the people who typically vote Republican.

***It would force them to spend time in whatever state votes republican, and less time in those states that vote democrat. If Utah is at the top of the list, then so be it. At least they would have a legitimate claim to being first or close to the top of the list. Today’s primary schedule is optimized for CINOs/RINOs/EstablishmentRepublicans/GOPe.
