Let's just keep it as a manga. I don't like when they make a movie or TV series and tone it down to the ground because "You can't do that on TV or in live action." If a comic is violent and has a half naked girl ... that is why people were drawn to it. You make a live action PG movie and cover her up and it sucks. Why? Because they took away what people liked about it in the first place and treat them like five year old's censoring what they can and can't watch.
A real Negima anime should have everything in the manga plus more. They can use music and the animation to really bring us into the Negima world. It would rock. But spin-offs and censored/toned down crap just won't cut it.
