Do you mean offset blister? These are the flags used at platform edges on rail stations.....
....the ones with the little bumps, not thes grooved pieces.
I think what you are proposing would look bloody awful, and, contrary to what you think, it will not make a significant difference to slip resistance. You would be better off with a bump-less textured flag, summat like one of these....
...or even a decorative patio flag.
However, it's not even necessary to cut out and replace the troublesome PIC. YOu can use a quality sealant with an added traction grit that will give the surface a slip resistance close to or even the same as you'd get by switching to a flagstone, and all with the added benefits of being cheap, simple and visually unnoticeable.
