Scale objects using attractor points

I have a question about scaling objects using attractor points:

I have stacked a couple of truncated octahedrons perfectly together, so there is no space between the surfaces and the elements do not intersect each other (see image).

Now I'm able to scale each element according to their closest attractor point, but in this case the truncated octahedrons intersect each other, or do not touch each other at all.

So my question is, does anyone know a solution to scale these objects individually, with the intention that the truncated octahedrons are still perfectly stacked (so no intersections and space between the surfaces)?

The rhino file and grasshopper definition are attached.
