I'm afraid there's no other practical way but create VPNs between
datacenters and tunnel your back-end Swift traffic. Although it
could be possible to use SSL (with minimal changes), there's no
authentication or authorization in Swift back-end services.
If you let attackers on your replication network, it's game over.
