I went to a small privately owned flooring shop recommended by one of my contractors. They were amazing and helpful after I showed them pictures of my situation. They have a product line from Republic flooring called SPC Max that is a LVP but made with stone powder and plastic resins. It is designed to never shift, not need any acclimation and most importantly is designed to handle 159º temperatures. There is a UV coating on the top layer as well. It is used here for people who use their homes for vacations or cabins where they do not leave climate control operating when they leave for the season. It has been installed in conversion vans and has not had any issues in the two years they've been installing it living under the AZ sun. They gave me an installer that would do the job. Regarding my existing floor, there is no warranty when not installed in a typical home and it had been glued down which they do not cover.
