Definitely not a good idea. It will burden the blockchain and it will impact on the Bitcoin transactions.

Have we forgotten about the Ordinals that are allowing users to mint the NFT directly on the Bitcoin Blockchain and what a mess it caused during the initial days? Imagine adding more smart contracts to it, instead of helping out Bitcoin we would end up screwing up Bitcoin's work structure and also the economic structure.

I think what we have at our hands is far better than what would we develop. I think in the past we also tried to fork it, nothing happened!
