Is any of this actually possible?

Question

Carbide ceramic ossification: The grafting of advanced materials onto the skeletal structure to make bones almost unbreakable. If coverage exceeded 3 percent of the total bone, mass white blood cell necrosis was common. In adolescents, growth spurts could result in bone pulverization.

Muscular enhancement injections: An intra-muscular injection of a protein complex to increase tissue density and decrease lactose recovery time. Increased the risk of a fatal cardiac volume increase.

Catalytic thyroid implant: The implantation of a platinum pellet in the thyroid containing human growth hormone catalyst. This boosted growth of skeletal and muscle tissues. It was known to suppress the sexual drive and cause elephantiasis.

Occipital capillary reversal: Increased blood vessel flow beneath the rods and cones of the retina. Increases visual perception. Known to cause retina rejection and detachment, as well as permanent blindness.

Answer 1

Knowing what technology we have now, maybe.

Answer 2

Where is your question? You just stated a run of contradictions, (i.e. "increases visual preception...as well as permanent blindness")

All of that is possible, if your oral fecal evacuation is.
