Moving Sketches up and down as if they were expanding.

I have a sketch that I want to be able to move up and down as if it were being inflated with air, so that I can show what it will look like when its fully inflated. Is there any way to do this? I would like to be able to show at different intervals, and dimension them at those points. I try to drag lines up, but can't get them all to move together the way I want. I included 2 pdfs, one of the original sketch, and one of how it may look inflated. Hopefully they help explain what I am trying to do a little better. Thanks for your suggestions!!SolidworksSketching
