Not necessarily a good idea.
Taken from Triathlete Europe;
"This is not to suggest that your back position is not important to aerodynamics. However, what matters is not how low it is but how you hold it. You want to strive for a slight curve in your mid-spine, almost like a hump. This will help integrate your aero helmet into your streamlined position. Specifically, it will help smooth airflow over your aero helmet, integrating your aero tuck into a neat little package and lowering your drag numbers another 50 to 100 grams.
There is a principle in aerodynamics that states that air likes to flow over curved surfaces as opposed to flat ones. Consider the toroidal bulges of aero wheels versus flat sidewall wheels. If you have a naturally flat back, work on curving your back into a hump, and if you have a humpback, rejoice, because it will help you ride faster"
