I think you're still confused on the difference between envelope-From and header From. SPF doesn't care about the header From, it cares about the envelope-From (and HELO). You can set the header From to the user's address without SPF issues. But that user still won't get bounces. Not much you can do about that other than forward the bounce to the user.
