It "works fine" to be sure, and it's possible that this is the only
physical shape possible for your surroundings, BUT did you verify that
there is no loss from drooping the top hat radials Vs not drooping the top
hat radials? My experience with many shapes of top hats is that it DOES
reduce the radiation measured in the far field.
Is that in comparison with no top loading at all, or purely horizontal top loading?
