If you try to do too much shaping in that situation, the holes will stick out like a sore thumb. I would stick to creating one or two relatively subtle features which give the holes some interest, and leave it at that. Most great courses have a handful of holes on uninteresting land -- think about the 6th at Ballybunion, or the first two holes at Westward Ho!, or the 9th and 10th at St. Andrews -- and those courses turned out just fine.
