Maybe the more-subtle/normal ones^_^

Normal ones like Lenna, Vincent, Selphie, Irvine, Ashe, Maria, Guy, Cecil, Cara, Terra, Tif[f]a[i], Beatrix, Vivi, Lulu, Tidus.

Not that I like most of those. Actually I lean sorta the same direction as yuna_elena. Rinoa is a pretty name Of the normal ones above, the only ones I'd really think about would be lenna vincent and terra. And terra would probably be spelt differently anyways.

(The secret is to make it their middle name. Like the chick I know whose middle name is Arwen. But her name is unique anyways)
