Here is a drawing of how I want to implement the new rad.
Is it possible airflow over the outside surface could create a low
pressure area such that an exit duct may not even be necessary?

It is possible. Might be worth a try. This I think might generate
a bit of thrust at high speed and a bit of a vacuum inside the exit duct
at low speed.
