One of the main challenges in our work is to try and form compositions with other services irrespective of whether the service can directly accommodate a one-to-one composition. If the service discovers that the type information is different but the parameter names are conceptually equivalent we need to use the type information associated with the two IOPEs and try to find a service that can take as an input a value of type A and produce an output of type B, which helps indirectly perform a conversion into the required type.

I thought about extending the Process Model and use a Composite Process to describe all the atomic processes that have been found (these could be several Web services located on different servers) but to use an additional property that defines the endpoint information where the atomic process can be found.

If I understand you right, you actually need not extend the current 
specs. There is a mapping between each atomic process and WSDL operation 
in the grounding. Therefore, if your composite process contains atomic 
processes with endpoints at different locations, their location can be 
extracted via the grounding file. There is no constraint that the atomic 
processes should point to WSDL operations from the same service provider
