Hi Kent.

Unfortunately no.

The reader itself will produce a uniform grid only if it is given an
xdmf file that defines a single structured grid. If there are two or
more grids it will produce a composite data set and then you have to
extract blocks to get each out.

Also, there is no filter in paraview that will merge uniform grids
together into a single uniform grid. There almost certainly is one in
VTK/Imaging, but it is not enabled and might be hard to use in
paraview because of the difficulty in making sure the data sets all
combine to create a nice structured data set.

CVS of paraview can volume render composite data sets, but only one
block at a time.
