The meaning doesn't bother me, I really like
Lydia which has a similar meaning.
I am not sure that the pronunciation you gave would occur to me, the Z sound feels a bit unnatural. I want to say it to rhyme with
Laura.
I like these combos:
Isaura Beatrice Isaura Clementine Isaura Daphne Isaura GenevieveIsaura Josephine Isaura Juliet Isaura Magdalene Isaura Penelope Isaura Vivien /
Vivienne
