Retrofit motion sensor to multiple switch, multiple fixture floodlights
Yes.  Wire the circuit with /3 cable and assign values as follows:


Black: always-hot
Red: switched-hot
White: neutral


Connect each lamp between switched-hot and neutral.  

The switch goes between black and red.  Keep in mind a 3 and 4 way switch complex basically equates to a single switch, provided it is a spur.  

Everywhere you site a motion sensor, it connects to all always-hot, neutral and switched-hot.   

Do not allow power to be severed from the motion sensors.  They need power 24x7 to retain their memory of day-night light changes. 

If you're trying to do this with combo sensor-lamps, they're not made to do that. You'll need to "hack" them to do that, and that's electronics.se's bailiwick.  Also it violates Code, which makes it off-topic here, and we see nothink.  Keep in mind many combo sensor-lamps create 12V internally to power sensor and lamp(s), as 12V sensors are much cheaper than 120V sensors.
