It doesn't matter how large an area you spread the impact over.

All of the kinetic energy contained in the flywheel, will upon failure,
be converted to heat.  Unless the containment vessel is large enough
to absorb all of that heat without melting, it will fail.  When it
does fail, in addition to the rapidly expanding field of very hot
gas, now you also have to worry about droplets of molten metal.

I wouldn't want to be anywhere near it when it goes off.
