OK ... this just clicked. It doesn't have to be a SIP trunk. Can I create a non-gatekeeper Intercluster trunk loopback?

I'm not sure of all the SIP parameters we need, I'm gonna start with defaults, but heeding the old rule of "never allow a trunk to dial a number that can reach itself" I was going to do the following: * create a SIP trunk with all cluster members as Destinations * check "Run On All Active Unified CM Nodes" * create a "SIP Loopback" partition and put only that partition into a "SIP Loopback" search space * in the "SIP Loopback" partition, create a translation for each route pattern with the failover destination Any thoughts, will this give me what I need?
