I support this.
Perhaps this could remain the random event it is, but each tier could be an unlock from the shop. So bronze ceremonial sword plan unlocks could cost 10 tokens, iron 20 tokens, etc.
When the random event appears, you would get the choice of metal that you've unlocked, and maybe or maybe not the choice of design I-V - this could still be the NPC request to fit the theme.
