I'm curious as to why there would be just a 2% chance of this working? Don't airlines have to rebook you (or they usually do it) if you miss a connection due to say, customs or baggage delay? What if I told them there wasn't enough time at JFK for a 3 hour connection (something that has happened before with me...) and I had to buy my own flight to LAS? Might they agree to not cancel the rest of the segments?
Don't get hung up on the 2%. That was someone's estimate of you happening on a friendly, competent, and empowered agent who would remove the LAS segment without affecting the rest of the ticket. But that is not going to happen. As others have told you, there is no way to make this work.
