q2wf had an 'anarchy' mode, where weapons could be pickups, sorta like a FFA mode. (some, not all. like the needler isn't a pickup, and only stock grenades stuck to their class definitions).
but that does mean a sniper could pick up a mega, a gunner could pick up a rocket launcher. its just FFA spam tho. plus the entities.def would need to be updated, but its sorta like q3's is now, weapon_railgin, weapon_megachaingun, weapon_pulsecannon, etc.
