I think the goal is not to edit the generated code manually but to keep
the code generator around and edit that if needed.

That's an interesting idea.  I tried to rewrite the Python code in Elisp
and it works, after a fashion.

The tree-sitter syntax tree is at a lower level than what libclang
offers and I had to rewrite the tree quite a bit to make it easier to
use.  I also pipe the C source code through the preprocessor first, so
that tree-sitter doesn't see macros.  With macros, it's even harder to
get some easy to use data structures out of it.

I'm not sure how to proceed from here. Anyway the code is here:
