Probably quite a bit more aggressive fit on the Bianchi as opposed to her current Dolce. Although if the Dolce is a smaller size than what she would normally be recommended, then maybe not.
I wouldn't expect to easily get the bars back to the Saddle to bar drop height her Dolce probably is at currently. So if a more aero position isn't desired, I'd look for some other Bianchi or another brand.
