Hi, Difficult to say for sure but typically the burners on adjacent to the walls have about 60% of the heat release as the center row burners. It might be worth a check to see if the outer burners spuds are drilled at around 75-80% of the center burner hole diameters (or have only 60% of the hole number). Depending on the burners details, it is usually easy to pull burners and modify. one at a time, if required. I've done so to replace spuds and just covered the hole while the burner is removed.
