Echo Shards used in a Smithing Table for Armor Templates

With the recent 23w04a Snapshot, armor got a cosmetic update. One of the things that can be used to make the new patterns are Amethyst Shards. Adding Echo Shards as yet another crystal to enhance armor would be very cool and add lovely color and detail. And, it would add another much-needed use to Echo Shards. Since Amethyst Shards share many similarities to Echo Shards, this would be a fantastic addition.
