Last time I checked, CDJ800s are not midi-compatible (in fact don't have a USB port for connecting to a computer). So the simple answer would be, no it will not work as there is not way to connect it.
Obviously you could go DVS with them, using a DJ 4-in/4-out external sound card and an external mixer or a controller with DVS compatibility.
