I've done this in a C++/CLI Clang implementation I've been working on. It
generates AST nodes directly from .NET types read from assemblies. I would
not say it was extremely complicated, but definitely tricky. There are a
lot of things that are not obvious and you will only find out about them
when the code crashes inside Clang internals, but if you're not afraid of
debugging it's pretty doable.

In case anyone is interested to look at the code:
