Let's stop for a moment and agree to a few things in principle.
1- If the voters in a state elect a candidate and the reps from that state decide to select the OTHER candidate this is nothing short of a subversion of the voters and of Democracy.
2- Most Americans would be opposed to something like this happening.
3- The current Republican leadership would definitely considering doing this in order to stay in power.
1 and 2 are obviously true. 3 is too much of a blanket statement. While I don't doubt some of them would consider it, it's by no means all of even most of them.
