Circle pack based on voronoi cell area

Hi all. I am trying to generate curves for a laser cutter with grasshopper. What I want to do is:

1. Choose cells based on their centroid's inclusion within an area

2. Circle pack circles within those cells equidistant from each other and their respective cell's boundaries.

I have figured out how to get the centroids of only the cells I want. But I cant figure out how to get the circles. Let's say I want 4 holes in each cell. But I want them all equally spaced within their cell - and I don't want them to touch the edges. How can I achieve this?

I have attached a screenshot of the cells with their centroids. These are the cells I want to put circles in. I will also attach my messy GH definition.
