That's rather pointless. If you store two secrets together, then they are effectively a single secret, and the TOTP just adds an unnecessary step to the authentication protocol. It's better to generate a long random key for your "password", store that in your keyring, and not bother with TOTP. Two-factor authentication is when you have two secrets stored in two different storage media, for example one in Gnome Keyring and the other in a Yubikey. If the keyring is encrypted with a master passphrase, then that's also two-factor authentication. The encrypted key stored in the keyring is one factor, and the master passphrase stored in the user's brain is the other factor. In that case a TOTP seed stored in a Yubikey becomes a third factor.
