The current PT version is on the left, while another variant using the same number of vertices is on the right. As can be seen from this view, the size of the plus shape is bigger (it extends a little further away from the centre) on the right (salmon colored).

The length of the orange bar (below) is closer to the shape on the right (above) than the shape on the left (above).

The black dots in the picture above form an almost perfect quarter circle.
The red dots above show the tapering - the narrowing of the axle main fins.
In this view (below), aided by the magenta plane slicing thru the middle, we see that the curvature at the plane is more round on the right than on the left.

Finally, the tapering is visible on the left (green vertexes), while absent on the right (yellow vertexes has no tapering).
I claim that without adding more vertexes, one cannot satisfy both a) and b) where a) is the tapering, and b) is the roundedness along the magenta plane combined with a larger plus shape.
