I'd do the new module with the new name, and the wrappers; as previous posters have suggested, and THEN ignore the old stuff. At least with the wrappers, users of the old API have a chance of being able to use your new functionality. If you change the new API, having the wrappers be made for a slightly different API is a whole lot more helpful than not having them at all, for people with the old code who might want to update the wrappers for you. I think it's worth doing in the first place.
