That divided tank would look really cool, but the shrimp will definitely find a way to hurdle over your dividers. The stainless mesh will act like a ladder.
You can test it out for a 30-60 days. Put some plants in each section, add the shrimp in the center part of the tank. See if any of them can make it past your custom dividers.
The babies will DEFINITELY find a way to get through unless you seal the edges dividers with silicone.
