Either way, as 2016 (and 1872 in the wake of Greeley's death) has shown, faithless electors probably couldn't rally around an alternative candidate anyways. So their best hope, if they dislike both parties' choices, is to prevent anyone from reaching a majority, but this just kicks the can down to the House.
That's what the founders intended. The whole idea of banning faithless electors turns the electoral college into a rubber stamp something it was never meant to be.
