In some responses that I made today, the idea may be present.

I searched (for about 3 minutes) to find older references to this 
thought, but was not successful. So here goes,

Brick splitting (I think was first proposed by Jeff Darcy) is to create 
more bricks out of given storage backends. IOW, instead of using a given 
brick as is, create sub-dirs and use them as bricks.

Hence, given 2 local FS end points by the user (say), instead of 
creating a 1x2 volume, create a nx2 volume, with n sub-dirs within the 
given local FS end points as the bricks themselves.

Hence, this gives us n units to work with than just one, helping with 
issues like +1 scaling, among others.

So, with just one disk, you'll be able to do some replacement like
Joe's solution
for adding a single brick regardless the replica count
