Yes.  It is whoever some work.  With the integration of ssh keys,
X.509 certs and smartcards in the GnuPG 1.9 CVS, most code snippets
should be available.  However they are not connected in a way to allow
what you want to do.  BTW, Hal Finney posted a description on how PGP
Corp. does this to the OpenPGP WG (ietf-openpgp at imc.org) on

My plans actually head into the other direction:  Take an OpenPGP key
and create an X.509 certificate from it.   This is easier because
OpenPGP has that feature of subkeys and thus it is better suited to
act as a general type of key repository.
