Mappers selecting weapons.

So I've done some thinking, would TWI allow us to create classes that have specific weapons. Meaning Me or other people would create custom roles, limiting and or modifying which weapons can be chosen for that selected player class. It'd wouldn't give a Russian Assault an MG42, but would allow the mapper to eliminate unlockable weapons, or selectable variants. Good example of this would be GuadalCanal, limiting the USMC Riflemen to Springfield rifles. I know TWI took the feature out (If I'm not mistaken).

Hopefully assuming this could be done, TWI would whitelist it or make it official.
