You've picked all the right stuff.
I'd go with a center four Pi to match the right and left mains. You can delete the port on a center channel four Pi speaker, just center the tweeter. Use three Pi subs flanking each of the mains, and if you have room on the opposite side of the room, add one or two more there for modal smoothing.
