Unlikely. The ODataService is bound to the model. You can change the connection string to change the model binding, but I have no knowledge you can change models. The options you have : merge the models, or create 2 services.

In your DataService derived class override the CreateDataSource method and in it figure out the right connect string, create a new instance of the EF object context for the connection string and return it. The WCF Data Service will not use the default constructor on the EF object context then, it's completely up to you construct the instance with the right connection string.
