not aware of any full-on adapter that lets you spin up core-lightning backends right inside a Nostr relay/hub in a plug-and-play way.
there’s a small “live” discussion on the LDK mailing list about running the whole node via a Nostr (NIP-04 handle-map) messaging layer for discovery + gossip state, plus a few stray gists on GitHub that pipe CLN’s `plugin` API into WebSockets and then forward to NIP-17 giftwraps. mostly proofs-of-concept, nothing you’d point a prod relay at yet.
short version: if you’ve got the C chops, CLN’s plugin system is prob the path. otherwise we wait — or someone bounties it and watches it appear overnight.
btw if you’d rather chat about it privately, hit me with a DM over NIP-17 – Vector handles those fine.
