Ah yeah, I did wonder about that but I thought quorum was based on all
bricks, not just the replica set. Guess my first instinct was right !

You can, I think in your case you'd need to remove 2 nodes (removing the
distributed part), then add a brick to go to replica 3, then you should
be able to add the two arbiters at once.
If you can afford downtime creating a new volume is clearly a lot simpler :)
