It’s not even as complicated as using a different network is it? Each NFT is only non fungible within the context of its specific ERC721 token. So you can just start a new token B and mint NFTs of token As content (eg cryptopunks) with token B. Of course if the original minter confers other privileges to holders then those can’t be replicated. But OTOH holding the original NFT doesn’t guarantee the original minter will continue to extend those privileges either!
