Generate Silverlight service proxies with same namespace

Question

I need to generate service proxies for multiple WCF services within the same namespace, which is not possible when using the Add Service Reference function of Visual Studio.

How can I do this in an automated way? I've considered using SLsvcUtil, but that would require that I make sure that I have my WCF services accessible, and, assuming I'm using the ASP.NET Development Server, I'd need to manually check the URL.

Ideally, I'd have some way of specifying an assembly, a service type, the configuration (web|app.config) and a target namespace, and then my code would be generated. Any Ideas?
