I did bit of testing of this some time ago. Not with the lastest Gluster
mind you... You can have different size bricks in a volume but you
should always have the same size bricks in a replica.

You say that there's enough space and no space will be consumed after
etc and in theory this could work. But I wouldn't certainly recommend
this kind of setup.
