Replication Setup With Failover Cluster

Does anyone have any advice for setting up multi-database replication? I have x number of mobile devices running couchbase mobile and I have y couchbase single server databases running. I've set up the single server databases so that they are already replicating with each other. I would like the mobile devices to treat them as a failover cluster. My question is whether there a best practice for setting up push/pull replication requests on the mobile devices with a failover cluster? I want to avoid a single point of failure but at the same time, I don't want to have to make y number of push/pull calls in my iOS code to replicate with my single servers. And I don't want to have to change code or config files whenever there are url additions, changes, etc.. Does anyone have any recommendations based on how they're handling this?
