Thanks for all your replies.
I spent more time with KiCad and I think I figured out the symbol lib problem that was driving my crazy... so this might actually work.

i use the inkscape plugin svg2shenzen from Budi Prakosa https://github.com/badgeek/svg2shenzhen. The plugins exports inkscape files to Kicad-projects. Sort of sidestepping the complexity of Kicad. I use those generated projects to directly produce boards at https://aisler.net/. I am using the svg2shenzen for designing my own boards and I also use it for teaching.
