Let's make it. We made it for Solid, but it got very complicated. Can we do better with Nostr?

Exactly

I think maybe the opposite flow would be more useful in the short term: a custodial key server that you can login to using your Google/etc account and it acts as a NIP-46 signer underneath.

Ok, it's an oauth2 login flow. When you "Login with Google/Apple/Github/..." it uses the protocol Oauth2.

Instead of having Google/Apple/... as source of identity, nostr can be this source of identity. It's "Login with Nostr" protocol for traditional websites (TIDAL could uses this for example)

It's a PoC of this idea
