"The lack of flight would make her inneffective against the Nephilim"
"Chimere’s suit can fly, but it’s not very good at it." It's not that it can't fly, it's just saying its not as agile as the others in the air. And, if you'll notice, this is hinted at being due to personal fear (of heights, specifically) rather than any weakness of the gear, so that it can be overcome later as the character grows (a recurring theme in my bio). The enhanced ground performance is just a side note (like how someone might have underwater performance as a side note that comes up once a season), and a preparation for a special move I have in mind later.
"none of her weapons have the trait(magitech) needed to hurt a Nephilim."
I was under the impression that when a MagiGear has a weapon, it is automatically an enhanced Magitech version (so the Katana's probably have magic cutting edges like your sword and the bullets fired by the guns are special and whatnot.) But, if I'm needed to specify that explicitly, by all means, I could. It's implied their magitech, because Chimere's emotions cause them to break quickly, which is not a thing that happens with any strictly technological artifact.
"they still have to have the "mecha musume" feel"
I wanted to use such a darkly aligned picture to really hit home her association with death and shadow, something that the anime style really has trouble doing in my opinion, but I can certainly change the concept around a bit to go with an anime picture.
