I've been working on a custom GSC mod idea for Black Ops 2 Zombies and had a theoretical question regarding the Origins Elemental Staffs.

Is it technically possible to add the Origins Staffs (Fire, Ice, Lightning, Wind) into the Mystery Box pool on non-Origins maps (like Tranzit, Town, Mob of the Dead, Buried, etc.), for instance with a very low roll rate (like a 1 in 1000 chance)?

Specifically, I'm curious about:

Asset Loading / Precaching: Can weapons like staff_fire_zm simply be precached via GSC (precacheItem()) on maps like Town or MOTD, or will client/server crashes occur due to missing models, sounds, or FX assets native to zm_tomb?

Box Logic Overrides: What's the best way in BO2 GSC to hook into _zm_magicbox.gsc or weapon selection tables to introduce a custom weighted roll without breaking default box functionality?

If anyone has experience porting Origins weapons to other maps via GSC or custom client scripts on Plutonium T6, I’d love to hear your insights or advice!
