Scale/Cull volumes

Hi guys, I am working with a set of volumes that once these intersect with stairs, the gh defition culls them. However, I don’t want to delete all of them, I want to know if it’s possible to delete one and scale the next one to half its size, like in the following screenshots. Does anybody know how to do it?

Thank you so much!!

This is the entire volume:

These (blue) are the culled volumes.

The red culled boxes are the ones I want to delete, and the blue to scale to half their size.

This is how I would like to scale the boxes to half their size
