Publish/subscribe in a request/response manner with WCF?

Is it possible to make WCF service work in request/response manner using WCF duplex channels?

Or is there any kind of automatic correlation between the messages when using WCF?

I want to be able to attach WCF service to a topic, and when a request comes, the service to return result, that will be transformed to brokered message and returned over the bus to the caller.

Thanks in advance!
