The only thing I can think of that NFTs could potentially add to Amiibos would be part of a form of DRM. The amiibo data is trivially piratable onto NFC cards, and there is a cottage industry of custom amiibo cards. Still though, if you pirate you don't get the actual official figurine, there are certainly other ways to implement DRM, consumers hate DRM, and despite Nintendo's well known aggressiveness in litigating and preventing piracy, they don't seem to care about DRM on amiibos, apparently because the data is not the core value-prop.
