There exists a RFC 5451 defining a header field Authentication-Results,
which is intended for just this purpose:

  Message Header Field for Indicating Message Authentication Status

It would be possible to create a plugin to prepare such a header field
based on results obtained from a DKIM plugin. It would also be possible
to enhance the DKIM plugin to do so. The implementation problem
that I see is that current mechanism for inserting header fields
insists that all added header field names start with "X-Spam-" .

You can open an enhancement request. Or use some other solution that
already provides such functionality (like an OpenDKIM milter, or amavisd-new).
