I'm not sure I understand what you're trying to do.  --export-secret-keys doesn't add or remove a passphrase.  If the key has a passphrase, the exported one still does.  If the key has no passphrase, neither does the exported one.

If your secret key has a passphrase, then "--armor --export-secret-keys xxxxx" generates an armored key file with a passphrase.
