I had the same pronunciation question
LYEkah, or LEEkah? I'd much prefer the former. I know Array mentioned Lycra, but my knee-jerk reference was perhaps weirder. I immediately thought "lycan," as in lycanthrope, like werewolf, like in Underworld. Odd thing to think of, y'think?
Anyway, looks like LYEkah to me, and I could see it on a girl. I prefer Lyra (LEErah) though.
