Buy extra comfort valves and put them where you like, and insulate as much of the pipe as you can.
That accomplishes most of what you want, the pump goes on the water heater, you can buy extra comfort valves separately, and you can just turn it off in mild weather.
So yeah it would use more power three or four months out of the year you would want to run it all the time for freeze ups, but the rest of the year you could just run it on the built in timer, or manually turn it on or off.
Your right it would not make the water get there any faster. Your wrong about the temp being dangerous unless you have young children or your an idiot who drinks out of the hot side tap. The owner should just spend $$$ on a Grundfos comfort pump with a crossover valve.
