That'd be just another trustodial mobile wallet, greenlight doesn't solve trust or issues of mobile offline-ness since there's still bi-direction with the remote signer (phone)... it's just a gimmick to scam the regulator... not a solution.
You're also still going to need integrations to other apps/services to get utility out of it... and that utility isn't going to improve by being just another trustodial wallet that can't help people actually earn sats.
I do like the idea of a language based interface, I've tinkered with it myself as that's really the killer app of "AI" in my view #1017929... but time is scarce...
Would be interested to collaborate if you back the wallet with Lightning.Pub, our wallet client is already bundled into a proto. A language interface over its RPC would be a great pairing given its powers.
