I've liked
Aelita for a while. I saw the Russian constructivist masterpiece "
Aelita,
Queen of
Mars" many years ago and was struck by how beautiful it was. So it's a name with artistic history and depth to me, which I enjoy.
Lita is a more approachable nickname for it, so it also feels useable. Aeli could be a short form as well, for a more "futuristic" feel.
Kalia is pretty but feels very empty. It's often hard for me to appreciate short, modern-sounding K-names, they are just not my thing.
Omeira means nothing to me, it feels like a pharmaceutical brand. I see that you described it as translating to "rich or prosperous" from an Arabic origin. Can you provide some examples of people who are named this? Where did you see it? Also your pronunciation guide makes no sense. Is it like "oh-MY-ra"? Or "oh-MAY-ra"?
