Adding 5 adults is only going to make the balance worse. Most of the weight is going to be in the back half of the car, making it sag even more and the front become unweighted further. You are also likely going to be exceeding the GVW of the car with 5 adults + gear + bikes.
I would be adding some helper airbags to the rear springs like I have on my Audi Wagon to help level things out if I were going to run a rack system like this.
