Obviously there is a company in Europe willing to make 20k expanders; they already did it once. I would just like to imagine Mary having huge, round, fake boobs, supported high on her chest, where they would always be in her view, so big that her arms cannot reach around or under them, so she must reach over; imagine all the challenges. Of course, this is only if Mary would enjoy huge boobs encumbering her every move and making her do things in ways other than normal.
