Question regarding non-rectangular facades

I have been playing around with CityEngine a little bit to see if we could use it to generate better 3D-models for our organisation. At the moment we have LOD0/1 bodies (see my first attachment) of all the buildings in our city (approximately 25 000), and we would like to use these existing models to generate (at least) LOD 2 buildings.  

So, I am wondering if it is possible to model non-rectangular facades using the Facade Wizard? I have only been able to model rectangular facades using it (see my second attachment, which is a generated facade of the "left wall" in the first image), which isn't quite what we want. Am I missing some functionality in the Facade Wizard, or is it not there? I'm guessing that it would be technically possible to generate a only a rectangular facade, and then generate the "upper triangle" of the wall along with the roof, however since the accuracy of our z-values is rather important for our analyses, I'd rather change as little as possible in the buildings geometry.
