Make floor intersect

Hi guys,
I want to make the floors intersect , they have the same XY points coordinates , I want them to intersect in such a way like in the photo is that possible , or is there any node that can help in such a process
I’d appreciate any idea/node that can help

The Element.SetParameterByName node(?) and change the Height Offset From Level(?).

Height Offset From Level could be story height - floor thickness.

This gave me the way to go , I have a complex script that Have sloped floors in it , But this would help , Thanks
