You can have multiple public/private key pairs for your public identities. Then you can maintain a secret public/private key pair that links your identities together. Encrypt the private keys of your public identities with the public key of your secret identity and publish them. Then all you need to decrypt any message sent to the public key of any of your public identities is the private key of your secret identity. Simply use your secret identity private key to decrypt the secret key of your public identity (which is a published encrypted message) and subsequently use that private key to decrypt the message that was communicated to you.
This could be easily automated, but I'm not aware of any implementations that currently do that. However scripting it should not be too hard. Finally, mathematically, in the bitcoin world, we've seen hierarchical deterministic keys. I see no reason why they could not be adopted in GPG also, although the bitcoin implementation requires use of elliptic curve keys. However, no implementation exists for GPG as far as I'm aware.
