Kind of wish that were true, but it would depend upon that state's election laws. At present, I doubt that any state's statutes would authorize such an action by its AG, and even if any AG did so, it would require, as you hint, a lot of guts.
That's why a federal constitutional amendment, or federal legislation along the lines I suggested earlier this thread, would, IMHO, be necessary in order to enforce the Article II constitutional requirements for the presidency and vice presidency.
We already have that in the Twentieth Amendment, Section 3. The problem is that Congress has simply ignored it's duty. Congress would ignore it's duty to any other Amendment as well. Besides that, you're asking the same folks who are complicit in the usurpation to pass an Amendment catching them in the act. It will never happen.
A better, more readily available approach lies in the state houses all across the country. It may not pass in every state, but if one or two passed this simple law, it would END the charade. See my post in post 101.
