That's an interesting idea, I'd say over engineering or further complicating
something that is more easily solved with an air/oil heat exchanger.  I will
say that I've been very happy with the tencentlife external oil cooler kit,
dropped my oil temps to remain around 210F  and pressure up to 40psi from
20psi at highway speeds.  Gotta make the engine last longer, without a doubt
all other things being equal.
