So you'd vertically stack two arrays? Same band? Why not just make your 
vertical elements 3/4 wavelength in one array, which has a pattern that 
is more like a 1/4 wave with a 1/2 wave stacked above it.

I think you're seeing the "1/4 wave V pol at ground level" compared to 
H-pol at 56 feet (which is close to 1 wavelength = 70 ft at 14.15 MHz)
