Thanks to all list members who answered. I decided to use the solution from the blog of Urs in the file "alternating-time-signatures.ly". It works very fine. It seems to me to be a more general approach than the similar solution from Joshua (thanks to him too).
The question of a good-looking position of the word "Welt" in measure 5 will take a bit more work for me, I have no experience with Null Voices. So I will dive into it in the near future. So far thank you all!
