I'm well impressed nufnuf77. I'll need to find out on the PHX Do how you find these fares exist.
One note of caution. The PHL-LAX 330 usually parks up in the maintenance area due to gate congestion and not needing the aircraft until the next morning. Transfer to T4 is via stairs from the plane and bus to the terminal so that will eat into your 56 mins transfer time at LAX, and you'll still need to get from T4 to Eagles Nest via another bus for the YVR flight.
