The idea of using the gauge theory paradigm of the SM to couple Quark-Lepton Model of matter and fields to Space-Time, as an emergent structure, is suggested. The color QCD quark fields, as SU(2)-connections of EM type, allows to define an adapted Space-Time metric compatible with the SU(3)-symmetry. It uses the double role of EM U(1)-connection, with the electric charge of the electron as a 4th color T, aside the RGB quark colors. The Quantum Flavor-Dynamics (Weak Force) corresponds to the break of symmetry due to finite subgroups of symmetry of SU(2), of Platonic type, and plays the role of a theory of transitions of states defined by principal quantum number in 3D, that we call "generation", similar to the case of electron transitions in an atom (2D finite subgroups). Gravity is a nuclear spin-spin dependent interaction, resulting from the fractional electric charge of quarks, as U(1)-components of the quark fields. This allows to derive Newtonian gravity as an emergent force, always attractive, by averaging over quark spin directions, providing a solution to the Hierarchy Problem. The compatibility between the fiber structure (SM Gauge Theory) and base connections (Space-Time and EM) is conjectured to allow in principle to relate the SM and General Relativity. This approach provides a unified approach to the four fundamental interactions. Several other remarks are included, e.g. regarding the relation between the emergent Space-Time approach and String Theory, GUTs, TOEs and Quantum Gravity.
