As I specified above, it's vital that the test be used outside of politics, too. If employers and academics institutions rely on the test for admissions, this would provide pressure to keep the test bound to IQ. If we further specify the test must be symbolic like Raven's Matrices, I think there is a good chance we could keep the test g-loaded. As for your second point, random selection is a vital to mitigate that possibility. A publicly verifiable source of randomness would be ideal.
