I really don't think Apple would want to open up Health data to the Google Fit. They want you to buy an Apple Watch, more than likely. I don't think you can sync Health data with a Fitbit either at this point.
At this point, no, unfortunately. You can export your data and import it into HealthKit, however, using FitnessSyncer. We'll put together a how to on that soon!
