What could we learn if we found the second moment of mass for a taurus and use E = mc2 to find second moment of energy?

We may be able to learn if a red rag has any effect ("taurus" means "bull")  perhaps you mean a "torus"? Sort of a doughnut shape?
The second moment of mass is just the moment of inertia. So we know what that is. E=mc^2 would be the restmass energy of something. Just blindly substituting a restmass energy density for mass in the moment of inertia calculation will still get you the (nonrelativistic) moment of inertia as before  just in different units.
