No your not, cyls fire at 180° intervals on each bank and other bank is 90° out of phase so you still end up with a firing pulse at each 90° at the flywheel unless its like a Volvo or others with odd Vee angle. From what I have read it is most likely based on the Coyote block which makes sense if Ford is gearing up for GT3 etc in the future. You could build it on the 'Big Bang' principle as you describe like some of the bike outfits, but IIRC that was done for traction reasons on the bikes, not sure you need the same on a car.
