Did your vet diagnose him with pancreatitis? If not, you are just guessing.
If it was my dog I would make an appointment with an Internal Medicine Specialist, I am assuming you have already had diagnostic testing and exam by your vet.
Get to the root of the problem. Diet is not medication. You need to make sure he is stable first before making diet changes, especially something as extreme as going to raw. Some info here http://skeptvet.com/Blog/category/nutrition/
