Eliana and Linnea are too similar sounding for me, and I strongly dislike Fisher, it just sounds silly. But otherwise, pretty decent as multiples go. It does give the vibe of one parent naming two of the girls and one parent naming the other two.
If I was naming the same:
Sylvie Eloisa
Florence Paloma
Imogen Aurelia
August Oskar
Camille Josefina
