Would a lower forward turret rescue the nine-turret design?

Would the design improve if only B turret superfired, with A and C at deck level?

If this refers to the earlier 18-inch design, the Nelson-style arrangement would improve it very little.

The proposed change leaves only B turret superfiring, with A and C at deck level. Nelson and Rodney provide the comparison for that layout. If the question refers to the earlier enormous 18-inch-gun proposal, this change would improve it very little.
