Make actors drop mostly broken weapons

[payl0ad]

I want to implement a mechanic that makes finding a weapon a little more challenging. Meaning that I do not want enemies to drop their gun on death - instead I want to replace the dropped gun with a Misc item (already baked some working nifs for that) that resembles broken down weapon parts and acts like your regular junk item.

 

Having browsed through the leveled item structure that attach to NPCs I can see that I could spawn the broken weapon by using an LLD but I can't exactly see how I would go about removing the intact weapon.

 

How would you tackle this? I think this should be possible with a script that monitors actors around the player but this just screams error potential to me. Is there a more elegant solution?
