Loop with Anemone

Hi,

For my project I want to optimize the shape and thickness of an arch for multiple load combinations. I use galapagos to optimize the arch by minimizing the bending moment by changing the form finding forces in x-direction. My next step is to implement an optimization of the thickness into the model. 

I use Kangaroo for form finding of the arch (1st figure)  and Karamba for the structural analysis (2nd figure below). I start with an initial thickness of the beams within the structural analysis part. After that I want calculate the real thickness (3rd figure) that is needed to not exceed a certain stress. I want to implement this new thickness into Karamba again which will change the self-weight. again. How can I create this loop?

Is this possible with Anemone? Or do I have to use another component for this cross-section optimization? And is this possible in combination wit Galapagos.

Thanks!
