There is quite long debate before: https://royals.ms/forum/threads/let-us-use-regular-items-as-cover-up-just-like-nx-items.118321/
https://royals.ms/forum/threads/request-fusion-anvil.10374/ It's already been denied as it's not possible. It doesn't exist in our source (v83).
I never understood this argument. How do Aesthetics go against the "nostalgia" half of the chairs or pets or NX cosmetics were not available pre-BB either.
No, but this is literally titled "Requesting Anvils". Otherwise, there's literally a thread right above this one for the similarly functioned NPC idea.
Fusion Anvil's don't really give a player any sort of advantages over other players, its for making an item have the appearance of another, which again i don't see how its gamebreaking for other players.
