I think more subtle is the key word here think more like this:
You could get a set of charge mechguns with a custom photon colour, name and description as well as stats:
Example:
KAJEX SUPER MECHS.
Lime green photon.
A pair of mechs made for a legendary gun master.
alternatively, items such as the heaven's punisher could probably be cloned and given a different class requirement with a custom name, so forces could use that specific weapon that only you own.
Btw items like this would be like this and named like this for everyone. Like chuk's very own special dildo.
