A novel approach in constructing deviations of the Kerr spacetime whereas
the symmetries can be preserved is presented. The method was applied
trivially in all known classical black-hole spacetimes tested, while
provides the possibility of testing and inventing deformations of Kerr in
a quick and innovative way. The methodology is based on earlier work by
