As Tim notes, not until 3.0.

The same as with adding a new cluster node with x-ha-policy:all in 2.8.x 
- the new mirror will be initially unsynchronised and will become 
synchronised when all old messages have been consumed. Producers and 
consumers won't see any side effects when the new mirror comes on line.

They will continue to receive messages.
