Morph extruded shape geometry end to another shape

If i have two different shapes and want to extrude a geometry between them is that possible? If not i plan to find the two closest points on flattened plane then start to walk the vertices of one of the shapes to the closest of the other shape. Any ideas on how to do it using current code/lib?
