Could you write them out using the ToJSon<http://code.google.com/apis/chart/interactive/docs/dev/gviz_api_lib.html#tojsonexample> instead of ToJSonResponse ? This would serialize a plain json object for each datatable. In the browser, you could load these json objects, easily merge them together (join their 'rows' array together, assuming the columns' definitions are the same) and create a single datatable out of the joined json payload.
