This will certainly be interesting to see if you can get this to
work - expansion and contraction rates of steel are different than
papercrete and rebarred papercrete fences have cracked near the rebar
points. Papercrete does have some elasticity however - if you weather
seal it correctly you can minimize the possible problem - Missouri
has less extreme weather than some other areas but humidity may pose
a big problem in your initial drying - you might look into a large
commercial dehumidifier.

An artist in Alpine Texas has had some problems with separation at
the point in his house that he used a wood beam because of the
expansion differences.  Have you built a small model using the steel
substructure to see if any problems develop?  You can put a small
model through some temperature extremes to see what happens fairly
quickly.
