If the Pixies turn out to be the second coming of the Moogles, I'm for it. (The ripping their wings off bit, I mean).

In all seriousness though, rather than some gaudy looking wings keeping us afloat, if we're talking minimally assisted flight, I'd be more inclined to look to something like a jetpack.
Or just the ability to outright fly. The WoL is more or less already Superman, without the flying part.
