I'd say that there'd be no problem whatsoever if:
1. The steel cladding is removed (temporarily) and stacked with lath
strips between the sheets so that there is no contact between the sheets
and any moisture can drain away (otherwise, trapped moisture can result in
"white rust" and subsequent premature corrosion of the (presumably)
2. The bales stacked and encapsulated in plaster to provide the straw with
an air/fire/rodent/insect barrier
3. The steel cladding panels re-installed.
This configuration would provide the plastered straw bale wall with a
ventilated rainscreen cladding, the drainage plane being the face of the
The ventilation air space would be provided by the thickness of the girts
(to which the steel is fastened) and the corrugations of the pre-formed
Since the plaster would never be exposed to rain-wetting, there's no
reason that it could not be an earthen plaster.

- Sometimes the steel cladding is also performing as a shear panel or sway bracing.
It may be wise to install some temporary bracing before removing the cladding.
