An idea i have had in the past but never implemented on anything is a system of oil 'catcher plates'. To explain, on the right side you have your kickout of a couple inches or more if you lucky , or dont mind having additional leak paths of plugs in your pan to access internal pain rail bolts. Lined up parallel(almost) and in line with you oil being slung of your crank you have flat sheets of metal angled slighty off parallel, perpendicualr to your wall of your oil pan. My unproven theory is that the oil being slung to the right side of the pan will hit these very slightly angled pieces of metal and due to the low angle the oil is slowed down gradually along the plane of the piece and in doing so it doesn't get hammered into a falt wall of your oilpan and at teh same time would still allow the extra 'air space' for some windage to escape the crank. The one thing in the back of my mind is wondering if the windage from the crank itself would try to push up the oil clinging to the metal pieces to the tops and try to throw it up into the crank throw area negating any positve effect....this is when you need a prototype and a high speed camera inside your crankcase...with tiny winshield wipers on the lense...
