I would suggest that only if you could stage them. Side ports optimized for low/mid-range power and driveability and have the peripheral ports activate at higher engine speeds to really open up the top-end. Unfortunately that would call for one hell of an intake manifold: 8 runners for the side ports, probably merging into less, and another 4 for the peripheral ports!
