A 2-of-3 multisig would be interesting. You control one key on the phone, a second key by a trusted bot (running on your node at home and auto-signing events based on rules), and a 3rd key offline as backup.
The only trick then is that the "multisig pubkey" is the actual profile pubkey.
Don't see a reason why it wouldn't work.
Yeah honestly. Vanity npubs is gonna fucking suck tho

Why so? Schorr's are linear, the concat of 3 or n pubs is still a constant 32 bytes...., and since u know all 3 or n u can easy decrypt.
