Sorry to hear about your health Mike hope things turn around for you (and you don't need to sell). Like those structures they look beefy.

The way I see it, I would keep the tallest tower in a overflow corner and lay other one pointing the opposite corner. Or take it a part and do a gradual decrease slope from the tall tower towards the opposite corner.
Or even better would do two decreasing slopes with an open lagoon/pass(pointing opposite corner to the overflow) running between them, where your tower by the overflow being the highest point.
