Well it would not be RAID 5, but you would get redundancy and 2/3rd the 
space.

Take each server and make 2 partitions out of the free space such as:

Server 1
Brick 1
Mirror 3

Server 2
Brick 2
Mirror 1

Server 3
Brick 3
Mirror 2

volume block0
  type cluster/replicate
  subvolumes brick1 mirror1
end-volume

volume block1
  type cluster/replicate
  subvolumes brick mirror1
end-volume

volume block2
  type cluster/replicate
  subvolumes brick2 mirror2
end-volume

volume unify
  type cluster/distribute
  subvolumes block0 block1 block2
end-volume
