This is great information. I use Genesis figures in C4D as well for comics. I do all my sculpting and customization in Daz and Zbrush first then bring the figures in as FBX files. I then link the joints from the rigged figure into custom controllers using the Visual Selector in C4D. With regards to figure height and other structure changes that may alter the general shape of the base figure, try creating 3 or 4 standard body types for males and females in Daz then you'll have an easier time editing in C4D. I'm currently looking at creating a python script for connecting joints to the Visual Selector to take some of the tedium out of the transfer process.
