There will be aerodynamic coupling between housing motion and ball motion,
unfortunately. How much, I'm not sure, but I suspect it's more than
enough to mess things up.
There are gyros which use electrostatic levitation of a spherical rotor in
a vacuum, one reason for the vacuum being to eliminate aerodynamic coupling
between rotor and housing. (They are complex precision devices, very
expensive, capable of extremely high performance, intolerant of shock or
high accelerations.)
