I don't think changing how gravity drive works is really necessary.
Could just make it as a new FTL drive type. There is no requirement that says that all FTL drives have to be for interstellar travel.
Not sure Hazeron solar systems are really big enough for the Elite: Dangerous's Supercruise to be needed. But I guess you mostly want it because atmos-dives are almost impossible with it.
