This is unclear to me.
Are you saying to create a new replica set with the newly added bricks
or with the older replaced bricks ?

If you add 6 new disks to the cluster by bringing in a new node with replica count 3 you are essentially are adding 2 replica sets. Since you can't have replica sets with bricks from same node, we need to get empty bricks from other nodes which require replace-brick operation.
 

This is not what I want. I would like to *add* bricks and increase
spaces to the same volume/replica set.

We essentially did add-bricks at the end :-).
