2d shape deformation using a boundary

As the title states in general i have a problem i am having a hard time resolving. The bloopy shape showing points scales and merges from the smaller white plines, my ambition is to have the scaling curve be constrained by the orange crv boundary as to construct a smooth interpolation between the two via a topography. i read this discussion and it touches upon the question, http://www.grasshopper3d.com/forum/topics/spatial-deform-correct ... the only issue is that it seems that mmany of the space deformation componenst rely on a box where as i have a curve boundary. In short i watn to constrain the red crv with points within the boundary of the funny looking orange crv. Thank you for your time, much appreciated
