http://www.stuff.co.nz/life-style/3023742/Women-with-male-names-do-better I found this quite an interesting read and thought you might like it seeing as you want a name which works well if shes a lawyer or a doctor as well as being cute for a little girl. Names like Georgina and Charlotte and Harriette which can be shortened to more masculine counterparts like George and Charlie and Harry as well being nice names for girls.
Georgina
Charlotte
Harriette
Thomasin
Simone
Josephine
Alexia
Theodora
Theres heaps and heaps when you go looking. I think Sienna is a really lovely name as well.
