Manipulating Curves for Building Form

Hello

I'm working on generating a building given a set of frequency curves (picture 1). I want to use grasshopper to manipulate these curves along their axis to later loft, and create a structural skin. what i had in mind is similar to the example provided. Any help would be amazing because i am a novice at Grasshopper but would like to learn. Plus the end of the semester is quickly approaching and without a building yet, stress levels are rising. 

Thanks!
