Creating feature pattern that varies in the shape depending on where the instance is?

I am trying to design a part to be 3d printed. There are few 100 cavities that starts at the bottom as vertical holes and expand in size towards the top. Shown below is a smaller set of 16x2 sets of holes. Finally, I require almost 500 holes ( 125x4 quadrants) like this. It is not feasible to individually make these holes.

Is there any way to create these holes automatically for all the array. I am very open to any other solution that could get similar results. For example, I do not necessarily need the holes in the frustum, I can have pipes extend such as shown below:

The solidworks part is attached.
