I just wouldn't. There are plenty of NOS leather racing saddles around, eBay and other places. Just for example, I picked Iscaselle Tornados, a red leather and a white leather, tan suede, and a brown leather Ariake Jaguar; '80s fast bikes and my fixie. Even NOS they were cheaper, lighter, naturals for riding in the drops, and just look 'correct' for those bikes, compared to Brooks. I'm not a Brooks hater, but racing bikes isn't their highest and best use imho.
