  In this work, we propose a novel approach to particle physics phenomenology,
which we dubbed as model benchmark analysis. We consider models that provide
vertices with similar topology but different Lorentz and gauge structure, which
we call isomorphic models. Under this setup, the coupling constants for each
theory have the same meaning, in the sense that describe the topologically
equivalent diagrams. Consequently, each model acts like a map of parameter
space into the observable space. This definition allows to group isomorphic
models into families with a common parameter space and perform calculations for
each model. As a proof of concept, we obtained some guidelines for the search
of leptophilic dark fermions at CLIC, making predictions oriented to
discriminate between beyond the standard model scenarios in light of possible
signals of new physics that could appear at lepton colliders. We present
different observables that can be useful to help discriminating between models.
