Good timing! I'm at a hackathon right now working with a group to come
up with a standard for adding Bitcoin addresses to OpenPGP keys. You're
correct in thinking that doing so with standard Bitcoin addresses is a
privacy problem, however we can also define new types of Bitcoin
addresses that address the privacy issue; stealth addresses can handle
the case where you want to pay someone without a formal payment request,
and integrating OpenPGP into the payment protocol handles the scenario
where you want to send or pay to a formal payment request.

Incidentally on my todo list is to come up for a reasonable standard for
taking X.509 certificates and using them to sign OpenPGP user IDs.
Essentially the certificate authority is then making the statement that
a keypair is authorized to sign on behalf of a domain-name, and in turn
that keypair signs that the email address on the user ID is correct.
It's a best of both worlds option in the same spirit of keybase.io
