This seems like a nice idea. One of the foibles of classical Chinese genealogy is its patriarchal emphasis. The given names, let alone the date of birth, of ancestral women, are rarely recorded in genealogical documents.
Western genealogy has a more egalitarian approach. Therefore, these embossing of fan charts for many Chinese genealogist will look more like hatchets or even lollipops than complete circles.
Good luck in your business venture.
Digital technologies mitigate against the necessity of Chinese literacy for initiating your family history research
