Overlapping Circle Packing with Fixed Radii

Hi there,

I suspect there’s a simple solution to this but can’t get there… I have 5 circles with fixed / pre-defined radii that I would like to pack together and overlap by a certain amount. Attached is very roughly what I’m trying to achieve:

Briefly looked at circle packing options, however these predominately rely on a boundary geometry to pack to, which is not the case here. My Kangaroo knowledge is very limited, however was thinking something along the lines of circle packing / magnet + collision to the smallest circle would be a starting point?

Any guidance would be much appreciated.
