Oh, and there would be no tides when the wiers on the lake are closed anyways.

Maybe, but I wonder if there would be enough fresh from N to S to justify the expense and effort. Unless you have a huge source of fresh water to draw from (like the Mississippi on the E side), then slowing/stopping the intrusion of salt from the Gulf inland seems to be the more promising approach compared with increasing the flow of fresh toward the Gulf (or directing it). Fresh water is a finite, limited resource. The salt in the Gulf is effectively infinite by comparison.
The solution to intrusion is not dilution.
Ultimately, effective barriers are needed.
