As I understand it, the idea is you put the data itself off chain but keep hashes on chain. Anyone who downloads the data can verify it by checking that the hash matches what is stored on chain.

Uh, no, you store nothing of sorts. Which is the problem. According to ERC-721 (NFT standard) you store exactly three things: the name, a cute pic and the URI to its definition file somewhere else (not even that definition has a hash, not that it would help anything).
