BTW, the neat thing is to use the extra pixels for zoom, when not
using them to capture more information from a broader field. The Nokia
808 does that, though its base behavior is oversampling rather than
multiple planes of focus. Nonetheless, it's really nice to have a
cellphone camera with an effective 3x zoom.

Speaking just from physics, no. Visible light wavelength is much, much
shorter than the spacing and size of those lenses. (Otherwise, you
couldn't see them well.) More, visible light has the difficulty that
it occupies almost a doubling of the wavelength spectrum, so radio
tuning tricks that are frequency specific work poorly on it. That's
also why there's such an art to lenses, and constant concern about
chromatic aberration and effects.
