What about the sideslip IAS errors when trying to control airspeed by
flying
so cross-controlled in a spiral dive?

And are there issues with torsional stresses on the tail boom at 90 kts IAS

(probably more from pitot cross-flow errors) with sustained full rudder? I

have no idea whether that is a worry in the proposed scenario but I am
recalling the ETA that twisted off its tail in a spin recovery.
