I will discuss preliminary exploration of modified Einstein Gravity under a novel alteration of formalism. We compare with recently published work asserting extra-universal origins for field content, and propose that Dark Matter and Dark Energy may be direct experimental observation of multiple semi-Riemannian metrics on the manifold of events. We propose a framework exhibiting geometric Dark Energy and Dark Matter candidates of the same form as those in the concordance model, and no additional terms. Assuming that the Friedmann model and any model within our framework can both accurately produce the observed spacetime geometry, we predict that $Trace(T_{DM,FRW}) = 4\Lambda_\{FRW} - 2\Lambda_r$ where $\Lambda_r$ is a model-specific scalar field determined within the framework.
