I think that is certainly _possible_, but I don't believe there is
anything that does that today.  You'd have to parse the Kerberos message
(which is ASN.1 and there are plenty of things that can handle that)
and extract out the realm of the server principal and route the message
appropriately.  One thing that leaps out at me is that by default a lot
of Kerberos messages default to UDP transport so that might be a bit
trickier to proxy them (but not impossible).
