Great idea, but I'm sorry to tell you that it won't work. The problem is that somebody hasn't told you the complete story. Electrons themselves don't absorb visible radiation. Rather, the electrons orbit a nucleus in a sort of cloud of energy levels and light is absorbed when an electron moves from one energy level to the next. Further, this light absorbtion does not occur in a broadband frequency (such as would be needed to create an invisibility field) but rather in extremely discrete wavelengths. So to create an invisibility field, it would not be enough to have a field of electrons (which would have to occur in a vacuum, anyway, to avoid collisions with air molecules) but rather a beam of many atoms. This beam would also have to be in a vacuum, and, as discussed above, would only absorb certain wavelengths of light. Further still, to create an atomic beam you'd have to supply energy to the atoms and this would cause the atomic beam to glow. Finally, you'd have to have the beam dense enough and this would be extremely difficult indeed. So great idea, but I'm afraid that the concept will not work. Thanks for asking!, and keep thinking!
