Is there a way of recreating this model using grasshopper in a larger scale

I would not recommend Grasshopper for this type of organic model. Unless you plan to somehow rationalize the form (say it starts from a cylinder with variable radii and then you create its wireframe with some kind of voronoi tessellation) you are better off modeling this manually.
