Choppa with mace/club/blunt weapons as watched on some NPC wield them is possible, so maybe loot table as that weapon type is available technically.
A Marauder can wield mace type weapons but a Chosen not(just sword and axe)? Why not? Same hit animation, and equipment same chaos type etc.
Same some NPC dwarf engineer wield crossbow type weapon which items are inside game database with 3d object + skin
so technically possible to improve gun/pistol and even crossbow for engi.
Other weapon variations also available in game database so the possibility in there...
Rare NPC weapons/skins are nice hidden goldmines of weapon diversities.

One day maybe a dev implement this ADD ON feature, which improves even original WAR. As game development gets advance maybe more dosens devs join us through the whole world and these less important features get them own development phase.
