I wish I could generate Nostr keys with my Coldcard Q.
Signing would be a pain though.

Surely you can generate keys from keys, so I can have a private key that controls multiple private keys.
Then I'd have an air-gapped store of all if my identities online, from which I can derived them again if I lose any particular private key, if I know the derivation path for constructing these private keys?

That's the part I'm missing. It's not only about deriving the keys but about a NIP that enables the issuing and revokal flow for a seamless experience of other users.
Is this possible already?
