Just looking at the first diagram, as drawn, it wouldn't work. Assuming that you're having the light curve through refraction (which is what was stated) when it left the cloud of dark matter/energy or whatever (that the index of refraction is not known for) then it could continue in a straight line.
With EA and bending of light, it'd bend UP, away from the FE.
Also, with the sun drawn as a sphere, and light rays drawn as shown, the whole earth would be lit.
