Those characters on that list were not THE main characters, but they were female leads. Of those, Tifa is the toughest, and I'd like to see another female that can fight with her hands. Terra and Celes were strong female leads, as well. Reina was a bit bland, and Rosa....well....don't get me started. Maria was intended to be a mage, but you could easily change that. I like what I've seen of "Lightning" (I know that is probably not her name) so far.
