Would not surprise me, but I think it more likely they will simply arrest Trump and fly him to Guantanamo. Then have a blue state Trump wins send an alternate delegation to vote for Kamala. Trump is Hitler and a Putin commie stooge of North Korea (odd combo that) and will need to be stopped by the deep state which of course will have all the evidence but cannot release it because it is an ongoing investigation and Trump is a flight risk so Guantanamo.
I think your fears are overwrought.
But, a blue state, or states, won by Trump need not falsely certify a slate of Harris electors. They can just not certify any electors at all...
Does election as president require a majority of the all the possible electors, or only a majority of the electors actually voting? I don't think the answer to that is clear.
Constitutional crisis? Absolutely. But the argument that Harris received a majority of the votes of the electors actually cast might provide, in the eyes of the left, a fig leaf.
