This isn't how it works. Port placement makes no odds unless you push them against a wall or the back of the cone shows through. There are a resonant device, and reinforce the low end loading the driver, and the low end is not directional.
Plugging ports lowers the tuning of the cab, you don't have to plug them all to mimic the response of a sealed cab, just drop the tuning to below audible. The Barefaced vintage has this option for that purpose.
