Yeah, I've seen some guy/girl conversions get eyes that make them seem like a totally different character. Ruby can probably keep her eye shape, really, as can most of the characters I suppose. The eyes either suit their archetype (Cinder with the sultry eyes, Ruby with the innocent eyes) or reflect some aspect of their character (Emerald with the innocent eyes, to represent the innocent facade she wears for RWBY), so they can sort of stay the same anyway.
