Just a silly idea I sudden;y came up with: since there is a Metal spell that makes materials as strong as still, literally, to the point of debuffing them if they are already stronger than steel, would it be possible for a Wild-Metal collaboration to device a spell that makes materials as strong as We-silk? @Boney?
Gold Wizards having steel-based spells is built on millennia of human history with steel. Unless you teach a We gold magic, that's not in the cards.
