How can I make this one curve gradually form into another one? 3DM attached

So I have two ‘end curves’ with different shapes. I am trying to make something like 20-40 curves in-between where one shape will gradually form into the second shape. The red line is an example of what one ‘in-between’ line may look like.


It is called TweenCurves in Rhino. Grasshopper has a tween curve component. If it doesn’t work out for you, you can get more advanced tween components from my plug-in Pufferfish.
