At the very least, it adds complexity, and an overhead in the
public-key cryptography.

Kerberos already provides mutual authentication and, as a side effect
of the authentication, a session key.  If you're going to use SSL as
well, the SSL session key needs to be negotiated separately.  RFC 2712
(Addition of Kerberos Cipher Suites to Transport Layer Security)
attemtps to address these issues, but I'm not sure how widely this is
implemented.
