A reasonable thought, but the purpose is to get the
oil pump load off of the distributor, however reducing its load may be good enough.
In my industrial work with pumps, both pressure and flow impact the load on the pump. To do this, you would likely want lots of volume available, but low pressure capability. A gear pump would not be the best type of pump. That's why I like the dry sump pump, as it is off the shelf.
