I'm not sure you'll have a lot of luck with this because fillets really mess up creating face groups. You might have some luck if you first create a set of face groups with a fairly course setting then go around the areas with fillets using the accurate option to refine the splitting. Not sure how much if any time this would save over recreating and just using the mesh as a reference.
Screencast should give you an idea of what I mean. I've attached the f3d at the point I got to in the screencast. Looks like the inside diameter and the side holes might take some time to compute using the accurate option.
You can see below the fillets are the problem, without these it would convert quite easily. I don't know if just using the accurate option would eventually solve with something usable if you selected the whole mesh.
