rheotomic surfaces question

Just by opening the def of Daniel Piker I get the result on the picture.

So I feed a mesh, from which I move certain points (z-axis) according to some fields. 

What I would really wanted to know is whether I could feed 3 or 4 slabs (surfaces) for example one on top of the other and then define some points (including Z coordinate) that would start creating connections between the slabs. For example a point between the first 2 slabs would make a bridging between them, another point between the second 2 slabs etc but not so much in a surface bridging technique but rather in a rheotomic surface technique.
