This biggest problem is I heard the copy NPC command has been removed from the engine (could be wrong on that) so it'd difficult to create. I guess in theory you could use a placeatme clone with frenzy on it and a disable time limit, but that would be subject to some bugs on many NPCs. Sadly I wouldn't know how to do that

. Hopefully someone can make it, otherwise we'll just have to use the console to tease NPCs with themselves.
