This is not an intended use of the JS API, so I don't recommend this. As
you've found, the JS service produces JS Objects not JSON.
Are you concerned for the load on your servers or ours?
Also, I think that I must reiterate my point since I really do love

The v3 API consistently promotes {lat: ..., lng:...} structures to
google.maps.LatLng objects (and likewise for LatLngBounds). JS developers
find this much more convenient than having to promote these structures for
themselves.
