there’s no reason you couldn’t have a hybrid torrent/blossom client:

create a v2 torrent with a bunch of file hashes stored on blossom. The torrent could even have blossom nodes embedded in it the way it embeds trackers.

Then a client could lookup these file hashes in the p2p network or on the blossom nodes. If all the blossom nodes go down then it can fallback to p2p. nostr:note128sjlckfqjs0x3juk3y0d375uy2vk47f56dxzgxvkcdddtpkrvtsjh9v9q
