If the surfaces are planar, you can extrude them using the surface normal vector - doesn't work so well with non-planar surfaces but can come close.

Otherwise, an offset surface with edge connections can work, though there may still be issues.  Rhino has capabilities for this that Grasshopper does not.

You might find this discussion useful, along with some code bits I posted there:

Extrude surface upon surface direction

Hi Jinping, maybe you'll want to chop a little of the top and bottom to have them flat, but here's a way using Offset. I mainly concentrated on the thickness question.
