I won't answer the best setup for your needs and preferences but I can say that they make low pressure (5-8 psi) psi fuel pumps.
You can get really good, low-pressure fuel pumps at Summit or Jegs, and if you want something fast and cheap to test your theory, you can get a low-pressure electric fuel pump (7psi) off the shelf at Autozone or Orielly.
They will have them sitting there behind the counter.
A supplemental low cost electric fuel pump at the tank is almost standard fare nowadays with cars that only drive on weekends and the standard fuel blends. Also, these pumps mentioned are very quiet unlike the traditional Holly Blue and Red pumps.
