I had this problem with one of my characters too. What I did was find a nickname I liked and then worked my way around that. I don't know if that will work for you, however.
Emiliana has a lot.
Em,
Emmie,
Emily,
Emma,
Liana,
Ana, and maybe even
Li.
Katherine (and spelling variants):
Kat,
Kate,
Kathy,
Katie.
Victoria:
Vic,
Vicky,
Tori, V, and maybe
Ria.
Gabriella: Gab,
Gabby,
Briella,
Brielle,
Elle,
Ella, and maybe Ri.
Cristina or
Crystal: Cris, Crista, Cristy, and
Tina (
Christina only).
Francesca and
Francisca:
Fran,
Frannie (which are both kind of dated but I don't know the setting of your story),
Frankie, and Cesca/Cisca.
Gwendolyn:
Gwen,
Wen, Wende,
Wendy,
Lyn.
Wilhemina:
Wil,
Willy,
Mina.
I know many of these names are feminine but some of their nicknames aren't (like
Wen, Cris,
Wil, and
Frankie).
