Two slanted wall connection problem

[mmm2]

I need to model the walls composed of a 300 mm bearing wall in the back and the exterior part made by a 50mm thick prefabricated element with a trapezoidal shape in the bottom and a rectangular shape in the top. If I use a slanted wall, the connection between the prefabricated part doesn't work. Do you have a suggestion to fix it? Please see picture 2 to see a visualization of what effect I would like to achieve made with morph.

The slanted wall is not cut properly

I don't think you well ever achieve the perfect result if you try rely on the automatic wall cuts to magically align.

This looks more like a task for the Shell, or even Morph, as you already discovered. (... or just go down the GDL rabbit hole 😄 )
