I believe your read of the situation is incorrect. The Constitution states that the winner of the EC is whoever has a majority of EC votes from the pool of appointed electors.

If WI, PA, and MI can’t appoint electors then the total number of electors is no longer 538. Total electors would be 492, meaning the winner would need 247 or more to win. If these three states don’t send electors, Trump still has 260 which is more than the 247 required in this scenario.

HRC cannot win by knocking these states out of the EC. She has to flip them blue.

I would also note that if the dems were to knock these states from the EC then campaigning against dems in those states for 2018 will be easy. Don’t vote D, they will disenfranchise you.

Or flip one state to blue and stall the other two in court.

You are both correct and I am wrong. The necessary majority is 50%+1 of the appointed electors, if a state doesn't vote, the necessary majority is (270-EV/2)
