Okay, I lived on the Chesapeake for 7 years. I've seen where oysters are raised. I don't see how you're going to sprinkle some smoked salt around and expect it to stay where you want it unless you used a big block of it. Then you'd risk changing the local salinity, which I do not think would be a good thing.
Not sayin' it can't happen. Just sayin' I don't see it.
