You could write a piece of Scheme to create the relevant module.
Namely, you could start with something like this:

  (let ((m (make-module)))
    (module-use-interfaces! m
                            (module-public-interface the-root-module)))

And then bind that to some variable accessible from C (or pass it to a
Scheme procedure written in C that will just store it in a C variable
that you can later access).

Most of the module system is written in Scheme, which is why using it
from C is not always convenient.  Also, large parts are undocumented but
one should try as much as possible to avoid using them in order to be
"future-proof".

Thanks,
Ludovic.
