Variable sizing/distribution of twisted boxes in SubD

Hello everyone. I’ve recently started using Twisted box SubD (or more like trying to). It seems pretty straight forward to get the twisted boxes from a SubD volume if you will. With some help from another plugin called Crystallon I’ve filled said boxes with Gyroid shells.
My question is if there’s a way to get smaller boxes in some parts of the volume and bigger in other parts and thereby controlling what a slicer would call “infill”?

My goal is for the modell to softer in some areas than other when printing with for example TPU.

Feel free to direct me elsewhere, but I couldn’t find info on this subject. Although I’m quit new to Grasshopper and this forum.
