There is no command for this. If you know the OpenPGP specs you may use
a combination of gpgsplit and a patched version of gpg to do this. This
is a common question and you may find more answers in the archive.
However, in almost all cases it is not worth the trouble. Just go ahead
and create a new subkey - OpenPGP applications should handle subkeys
automagically; the interesting piece is the master key (with the
fingerprint) and the signed user ids.

That won't work in practice because you would end up with a different
fingerprint. What about fixing APG?
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
