Parametric brick wall

Hi everyone!

After a while of watching tutorials and traying out stuff on my own I managed to make a nice brick wall with a hole inside.

I can move it and change the shape of it.

What I would like to happen with it, is not to make a hole but just increse the spaces between the brick, where the hole is.

Has anyone an idea to acheve that with my script, or do I need to start over?

Thanks for help.
