gpg --quick-add-key should be able to add an existing key as a subkey, not just generating a new one
Open, NormalPublic

Description

for example, if i've loaded my ssh key into my gpg-agent, i'd like to be able to tell gpg to associate it as an authentication-capable subkey of my OpenPGP certificate.

i'm thinking that if the algo parameter to --quick-add-key is a keygrip, then it would find the key directly in the existing keyring(s) and attach it as a new subkey.
