There is only one potential flaw in this "floating mounting" technique:
How do you position the first (left in your case) chip?  You realize
that if you don't position it square (and there is no guide to help you
position it square) then your pair will have a rotational error, no
matter how well you align the second chip with the first.  This is
the biggest fear I have when I float-mount chips from the ISO Duplex
camera.  For regular 35 mm chips from a stereo camera I use an
alignment jig that has an edge, over which both chips slide.  This is
equivalent to the rails "driving a plastic hunk" in the RBT mounts.
