Not that I think that the state would ever want to spring for the cost, or be able to get the requisite permits if they did, but what about filling in the Witches as a location for your sandy island?
The Witches would provide a nice solid rock foundation, the water there is not too deep

, it's already a high traffic area, and sand instead of rocks would provide a safety improvement into the bargain!
By the way, I like your new signature line!
