I'm not sure, in all texts I've red about her she is specifically tied to drows - they've became drows because of her after all. Plus she hates surface elves and drows kill them for her, so I can't imagine her accepting any "normal" elf. Maybe she could use a surface elf, but accept any of her ex-husband "children" as her own? Never :P
Your problem is that you expect consistency and logic from a chaotic evil goddess who is also a narcissist.
