I think that if they weren't told, most people wouldn't notice. People are notoriously bad at noticing things, in my experience, so I don't think that it'd be a problem.
I love
Nadia and also
Nadya. However, Ayden is horribly trendy and far too masculine for a girl. If you like names that mean fire, why not use
Azar,
Nina,
Shula, Pyrrha, or
Fiammetta? They all mean fire, and they're all actually girl names.
I really like
Azar, actually, and the similar-sounding Azucar.
Azar
