sync en4 internal cues

is it possible to synchronize the internal saved cues from a en4 to a onyx show?
so you can use a merger to have a backup in sync with show, and if the main console is lossing connection in anyway, the en4 gives dmx.
so we think about a web control automation or use external triggers, but if it would be possible to put en4 to xnet like another onyx running as backup would be absolutely great!
