Seeking evidence for dark matter as field by gravitational lens

Dark matter is inferred about galaxies, for instance, by the application of Newtonian gravity, in two ways, the classical and a proposed form (1,2). The classical form suggests about a doubling of the visible disc, where dark matter is assumed particulate mass/energy adjacent to the disc. The proposed form indicates dark matter as possibly a field of pure gravitational energy existent one order of magnitude beyond the visible disc. The origin of this field would be the adjacent large-scale cosmic voids, which are undergoing accelerated expansion; in Newtonian terms acceleration implies force -- a force pointing toward the galactic supercluster void shell, the shell containing clusters of galaxies.

The field hypothesis could explain the inability to detect particulate mass/energy by any type of instrumentation. The hypothesis might be tested by the manner in which the gravitational lens effect about a convenient galaxy, or other astronomical body, is apparent in the two cases. In the classical form, dark matter should be concentrated about the galaxy, and in the proposed form, dark matter should be much more dispersed and far reaching. The gravitational lens patterns as well as degree of deflection of incoming light by the astronomical body, accompanied by it's dark matter could be markedly different in each case. (Specialists, please comment on the efficacy of such an experiment.)

Also, it would be interesting to know how general relativity would give account in such a comparison, reminiscent of the starlight deflected by the Sun experiment early in the previous century, before "dark matter" terminology.
