Express DMX IN / OUT

Can I simply use the DMX IN / OUT with two consoles and a single data line to control a large plot with a singular cue list?  

I have used MIDI to connect a Hog 2 (movers) and Obsession (dimmers) but each had a cues list sometimes with dummy cues.  There was also a programmer for each desk.  I don't want to follow this model as I am the only programmer.

I have access to an Express 48/96 (movers) and an Express 24/48 (dimmers).  Total of 288 channels.  How do I use one desk to control the other?
