I got an idea, which shouldn't be too difficult but would add uniqueness to each individual player.
Why not provide suit model options? Instead of everyone being the same model but differently colored, why not allow the option to choose your suit model? (Could be found under the Environments tab and near settings)
Perhaps something like:
-Combine Elite (Default)
-HEV suit (custom downloaded model)
-CS:S GasMask (requires CS:S obviously)
Those would just be the default options for players to choose from, but as always if people wanted custom models to be used on their server instead they could go into your lua file and edit them themselves.
The reason I think multiple options should be available, is simply so that color isn't the only thing that makes people look differently from each other. Plus its fun, if anything, to choose your space suit /ect.
Edited: Sorry for the Bump :(
Also, I'm not sure if you are aware of this but whenever I spawn the LCDevice from the Entities menu I receive this error:
Another note, the HUD doesn't show up after I respawn. Even if I take off the helmet and put it back on... The HUD never returns after dying.
