I like your ideas.Certainly the AOS a part that needs improvement.
I am not convinced that physical capacity is the biggest problem.
The internal part that fails and causes the smoking is a small 'rubber' diaphragm. Replacing this diaphragm with a piece of Viton would probably make it last forever? Easier said than done !
There is another situation that causes the smoking -violent turns with very sticky tires.The oil just 'sloshes' up and overwhelms the system.
A deep sump+horizontal baffle should help that problem.
I plan to try the Viton idea if I can get a failed AOS to experiment with.
