Generating DataContracts with exact namespace as in XSD

Question

We have to integrate our project with back end Oracle Platform. And this integration is via various WebServices. I have all WSDLs and XSDs for all these integrations. And I need to generate DataContracts from these WSDLs & XSDs.
Now the problem is, mostly all of these integration shares some common data types. and I want to reuse them.
e.g,

Integration1: oracle/common/commonDataTypes.xsd
              oracle/integration1/someXSD.xsd
              oracle/ebo/baseTypes.xsd
Integration2: oracle/common/commonDataTypes.xsd
              oracle/integration2/someXSD.xsd
              oracle/ebo/baseTypes.xsd
Integration3: oracle/commonDataTypes.xsd
              oracle/integration2/someXSD.xsd
              oracle/ebo/baseTypes.xsd

in this case, I want to reuse the oracle.common.CommonDataTypes between integration1 & 2.
so far I have tried WSCF.blue & WSCF. But these tools generating all the code in a single folder(and single namespace) and not following namespaces.
I want to generate classes under namespaces like oracle, oracle.commonData, oracle.integration1, oracle.ebo etc. so is that any way that generated Datacontracts follows exact namespace notation as the XSDs have?
