We present a speculative electromagnetic scalar-gravity framework in which the angle θ between the electric and magnetic field vectors is promoted to a dynamical Lorentz-scalar field θ(x), whose spatial gradient gives rise to effective gravitational phenomena. This version (v1) extends previous formulations by addressing key consistency questions in the quantum field theory sector. In particular, we show that, within the present framework and in Lorenz gauge, the BRST structure reduces to that of standard QED. As a consequence, BRST nilpotency follows directly, and the ghost sector decouples at tree level. The resulting spectrum is ghost-free under the stated assumptions. Tree-level analysis further indicates compatibility with standard requirements of spectral positivity and microcausality, while full one-loop consistency remains an open problem. On the classical side, previously obtained results are retained: a regularised covariant definition of θ with λ fixed to the Planck length, derivation of test-particle dynamics in the weak-field limit, and an explicit calculation of light deflection consistent with Solar System constraints. The framework is presented as a falsifiable candidate theory, with clearly identified derived results, assumptions, and open problems, together with a structured research programme and explicit observational tests.
