Yes, that's exactly the kind of loose binding I would opt for. Good thinking!

There's still the question of how to write the C++ bit. Longer term, 
generating C++ at run-time using the LLVM's CLang project might be an 
alluring option but I'd still value process separation as long as unsafe 
languages are in the mix.
