If no good then to get the curved transitions you will probably want to tube a morph plan along a path.
I think I would start with single line morphs to build a frame first to get the shape.
Then tube a morph polygon along the framework.
If you just want the general shape not worried about the curved joints) then columns and beams along the morph frame.
Maybe just overlap them all at the end, convert to morphs and the union them.
The beams and columns are better in 23 as you can control the end angles better.
