one possibility is that both of your combined proxy/registrars have
their own location tables and you forward registrations from one to the
other.

The problem with that is horizontal scalability brings noise. If I have 10 of these things, the SIP replication alone would be flooding the network.

If you are running in an environment where you can use multicast it might be an option for you.  Multicast the registrations from the edge proxy to the registrar cluster.  If not maybe you can get the registrars to replicate to each other on a separate interface from the interface facing the edge proxy.
