Sounds like far more hassle and expense than it's worth.
Along the lines of what @bmx_fred suggested, you could also find a Nitto NJ-89 stem (1-1/8", but designed for women's keirin, so NJS approved, if you're stamp collecting), or try one of these from Drew at Hubjub: http://hubjub.co.uk/index.php/store/stems/zenith-stem-detail
Really good quality; about 90% the quality of appearance of an NJ-89 for about one fifth of the price. Bought one for my girlfriend's Bianchi Pista Concept before it was stolen.
