A PID controller with a heater or cooler of a single reservoir won't do?

(e.g., an isobaric or isochoric process), you will need a large number (technically, an infinite number) of reservoirs at different temperatures.
That could work to perform a reasonable approximation of a quasi-static process on the gas, but it wouldn't constitute even an attempt to perform a reversible process because heaters and coolers generate entropy by design.
