You can't enchant your bones. OK, you can BUT it's going to cause problems. Bones are not unchanging things in a body and not just for structural support, no matter what Wolverine comics will have you believe.
Bones shift, bend, stretch and turn at every move you make; that is how your body absorbs stress from all motion. If they can't, that stress will go to muscles, ligaments and organs, causing damage. And if they can and are enchanted items, that twisting-around might impair their function.
Bones are continually built up and destroyed at the same time as a way for your body to store and recover salts, minerals and other substances. If they can't, you die a fairly painful death. If they can, those enchantments are not going to last long.
Bones are hollow and many important things happen inside them, not the least of which is the growth of new blood cells. If you fill them up, you die a fairly painful death.
