The RULED shell is the only tool that can transform from a starting profile to a different ending profile.
It will create a surface from the start shape to the end shape if that is what you want.
You have no control of the transformation in between so if you want to go from rectangle to hexagon to octagon to decagon to circle, you will need a shell at each change.
But it sounds to me like you will have to manually create the beams and columns at each step to get the shape you want, and then skin them with morph surfaces (or maybe even roofs) if you need to connect them.
