case 2: The same motor at 4S at EPA 67.5%. Assume that the motor is running at 40K rpm which is at the max efficiency rpm. Motor will be running cooler and not overloading the esc.
Will the above be true?

its just a silly backwards way of doing things. you first figure out what batteries you will run, then match your motor kv to that. If you're overvolted get a smaller battery, don't turn your epa down to compensate.
