gpg-agent forwarding / create stub keys from full key

I'm trying to use gpg-agent to sign/decrypt data on a remote host 
without storing a copy of the secret anywhere except on the local host. 
In general this should be possible since it's more or less how the 
smartcard support works.
Unfortunately gpg refuses to operate without a copy of the secret key in 
the keyring. From some mailing list posts I gather that gpg creates 
"stub keys" for keys on smartcards. Is there a way to generate and 
export such stub keys for "regular" secret keys in the keyring?
