The kinds of things you're talking about don't have any plausible method of action - it's not a matter of our brains or bodies evolving to be able to do something. To get what you want, we either need to be wrong about large parts of physics, or at least unaware of some pretty significant stuff. It's not like, for instance, flying, or breathing underwater - it's at least conceivable that human beings could evolve into something that flies, or has gills, albeit pretty unlikely.
Another point, Evilution takes a *long* time. Millions of years. For us to evolve into something that flies would take just as long. Not counting genetic engineering or something.
On the other hand, selecting for existing traits can be a lot faster. Lots of examples of this sort of thing already - most domesticated animals and plants show major signs of this sort of selection.
