The women's '51' has a reach 2mm greater than your 48, but 2cm more stack. So you'd loose most / all the spacers and reduce the goofy seatpost-as-long-as-your-seattube somewhat.
Hypothetically if you got one you could go from 'acceptable, kinda' to 'pornworthy' after a respray. But who has time for that etc.
