I've done that, except with a 737. Typically the airframe is
overstressed on the way back down. Either you end up going too fast, or
you shear off the wings while trying to level out, or you get into weird
oscillations between semi-stable flight and vertical movement.
Fortunately, it's not a problem that is ever likely to arise in real
life, since getting up to 90,000 feet in a 737 would be problematic to
begin with.

I've noticed similar problems and instability when trying to
substantially exceed the service ceiling for the aircraft, even well
below 90,000 feet.
