OP is saying that there's no risk, because you can wait until after the election, but before the new term begins (i.e. before January, 3). Trump could still nominate then, and the current Senate could confirm.
But this is also exactly why this gambit doesn't really work - because the voters know that whatever happens at the polls, the end result is the same. They could hold voters hostage to the Supreme Court nomination back in 2016 because there was a split between the president and the Senate that blocked either side from getting what they really wanted until the next term.
