I haven't run a ton of complicated DR architectures, but how complicated is the controller in just hot+cold?
E.g. some periodic replication + external down detector + a break-before make failover that brings up the cold, accepting any unreplicated state will be trashed and rendering the hot inactive until manual reactivation
