Not I. I assume that if Fetterman dropped out tomorrow due to health or being crazy that they would slide someone in who is not a communist basket case and that person would do even better than Fecalman.
Not up on PA rules for replacement. Usually if a candidate steps down or dies the party can nominate someone to take their place without it going to voters. Not sure on a state by state basis. But emphatically no. If you can't beat fetterman, Oz would struggle even more against the new opponent. Of course Oz is a New Jersey guy and I do have my biases, but that does not make fetterman look like much either. He needs to get a real job somewhere instead looking like he is doing gaming in his mom's basement all day. Frigging loser. He may win, but he still be a loser.
