I’d like to see the source material for this claim. I would find it hard to believe that they would leave the door open on such an easy technique to throw the vote and let another candidate win by simply slowing the vote counting process.
In Wisconsin if the vote is not certified by 12/13/16 then the state legislature will assign/appoint the electors. Not certain which house. Since both are pubbie it should be OK. This information comes from posts on FR. I don’t know about the other states involved. Another post indicates that in Wisconsin the requesting party must present prima facicia evidence of voter fraud in a court in order to get a recount.
