Unless the vessel is spinning at a significant fraction of the rotors
velocity, there will not be time to transfer a significant amount of energy
to it, before the shock waves tear it apart.  Then again if it were spinning
that fast, it would already be under a lot of stress and would need less
of a shock to cause a catastrophic failure.

Sounds like your working on the idea of multiple flywheels, so that each
wheel needs to carry less kinetic energy.
