so you rent a bulldozer and push some of of that shoreline sand in and build up a shallow area...no problem! lol
Any sand you push in like that would migrate downhill to deeper water. To maintain a shallow area long-term with sand, nearly the whole pit would need to be filled in so the bottom sloped gradually all the way across. To me, a pit is a situation to avoid. I've fished in pits before that were stocked. Fish were stunted and lacked forage.
I am not meaning to be purposefully negative, but being realistic.
Waters with steep banks leading to great depths and little shallows tend to be unproductive. The depths below a few feet will be anoxic. Sure, it could be aerated, but that doesn't solve the underlying problem.
