Gravity lenses only occur where spacetime warps around a very massive object. This causes the rays of light to be bent. Sometimes this bending will result in the magnification of the object, while in other situations it only distorts the object.
They do not function in the same manner as an optical lens. Neat idea though.
acually they do,
a recent discovery in optical lensing
A gravitational lens not only distorts the image of a distant object, it can also act like an optical lens, collecting and refocusing the light to make it appear brighter. Wondering if gravitational lensing might be responsible for the unusual brightness of these objects, the Herschel scientists teamed up with CfA astronomers Mark Gurwell and Ray Blundell to use the Submillimeter Array (SMA) to help resolve the question through its superb spatial resolution.

Gravity Lensing Brightens Distant Galaxies
Astronomers who survey galaxies in the distant universe are getting some unexpected help from gravity, according to a new study.
In a presentation at the American Astronomical Society meeting this week and a related paper in the current issue of the journal Nature, researchers say that as many as 20 percent of the most distant galaxies currently detected appear brighter than they actually are, because of an effect called "strong gravitational lensing."

Mars, Asteroids, and Jupiter's moons are the only worlds we have a chance of visiting in person.

Wouldn't the lens around our solar system and the lens around another solar system cancel each other out... One magnifies while the other de-magnifies.
