I see where you’re coming from (with the naive formulation of the proportional charges/masses and inverse square law) but at relativistic and microscopic level they are very different (including, as another poster observed, the remarkable property that a test-mass accelerated by a gravitational field is unable to observe that field, which is a formulation of the famous Equivalence Principle).
