Motion sensor to replace 3 and 4-way switches

I have a stairwell with four floors.
There is a 3-way switch on the lower floor with traveler wires to to four ways on each floor so I can turn the stairwell lights on or off from any floor.
The light switches are not in the stairwell but in the room off the landing.
I would like the lights to go and off automatically as someone enters the stairwell. I cannot use in wall motion detector switches because the switches are not in the stairwell.

Can I put a motion sensor on each landing and connect them to each switch? I guess the would replace each switch.

I am concerned about this working with the 3-way/4-way wiring.

Can I do this and what sensor would do this job and how would I wire it?

Here WATTSTOPPER VACANCY SENSOR MULTI-WAY WALL SWITCH RH-200-W-CS WATT STOPPER / LEGRAND , as well as other places I Googled, you can find the switches. I am not sure how they will work if two people enter the area at the same time. Nor do I know if they can be loaded in tandem.
You won't like them since the light will probably go out before you transverse staircase (should you not be able to install one on each floor). You may not like the price, either, at $55 each, that's a lot of $ to spend on switching. Remember, opinions are free and worth every penny of it.

From the best of my knowledge, you'll be able to replace the 3-ways but I doubt you'll find a 4-way.

They have them but, AFAIK, they require a neutral.
