Um, I don't think these accelerated (rotating) frames can be equated so simply via special relativity. And if you're thinking of the equivalence principle, remember that's only true in the limit; in extended frames tidal effects will easily detect which frame is moving. Note that Mercury, for example, revolves in the Schwartzschild geometry near the Sun, not the other way around.
