Feeds import from Restful Web Service module output
I just want to post my plan for everyone to review and response.  After days of no response, it does mean I'm having a crazy idea.

I've re-think my solution and came up with writing my own custom module to do the data copy from one content type to another.  It was easy than I expected.  Copy of data from one content type to another is very easy if the both field type are the same.  It's a straight assign of field from one node object to another content type object.  That's it.
