Extrude rectangle along planarized polylines

Hello,

I would like to extrude a rectangle in the first instance along planarized polylines of a dome e.g 4x4cm structure to create to supporting structure.
The next step would be to apply a teardrop shape.

In the second step, since I have a output of different cross-section sizes (calculated by karamba3d), that I would like to apply to the dome, I wonder how to create different cross-section sizes (maybe using a loft for a different sizes along a line?)

The crucial point is altough to align the cross-sections along the planarized hexagon.

Thanks in advance and BR
