I am not sure if I understand your setup correctly, but let me 
explain some possibilities.

The LCX has a DMX input from which you can merge/replace a range of 
channels (say ch 50-100) with the LanBox light channels. You need to 
place fixtures on the stage which are corresponding with your ETC 
setup, and create 1 cue with all those channels in it, set to 0.

If you load this ETC cue e.g in layer A, and you have DMX input 
mapped to layer A, the ETC channels will passed to the LanBox DMX 
output. All other channels of the box can be used in lower layers; 
the ETC channels override the box channels, as ETC is in the top 
layer.

If you set layer A in HTP mode, the output will be the highest values 
of ETC or LanBox for a given channel.  If you drag layer e.g. layer B 
above layer A, cues running in layer B can override the ETC channels.

BTW One LanBox-LCX can be controlled with multiple computers running 
LCedit+, if the box and computers are on Ethernet.
