Sorry, but The organization you admire so much would not be picking the delegates. Legislatures would.
And you’re wrong that the legislatures are not compromised. They ignore the Constitution the same as members of Congress do. Virtually all of them, blue or red.
It is not written in the Constitution that legislatures will pick delegates. Nor is it written in state laws that they will do so.
And again your extrapolation that all state governments are compromised and corrupt is in error. If that’s how you think then you might as well get on your knees and beg.
