From your description of her measurements - I would suggest the Orca, maybe with a shorter stem (90 or even 80) rather than the Diva. Is there a special reason why she want a women specific bicycle?
If your Orca is a size 51, try to sit her on yours and see if that can be a good fit. My guess is that she may need the 54. If 51 is too small and 54 is too big - then you may want to have her sit on some bikes other than Orbea.
Is any of the bike shops in your area a BMC dealer? Their bicycles are custom made in Switzerland. Great carbon fiber bikes, and great custom fitting program. you can take a look at their models on http://www.bmc-racing.com
Best of luck!
