As per my comment here, I think that (at least theoretically) the same code that runs PortableInfoboxes could run navboxes. As said there again, the only changes that would need to happen for that to work is the addition of the "show/hide" button and the width change. :)

EDIT: Oh yeah, it would also need to just not read most, if not all, transclusion parameters.
