Negima / Nanoha crossover idea

[Berk]

All indications are that Hayate made a full recovery, we see her in the flashforward of A's, only a few years later, already walking (and apparently running) with no trouble at all. Her magic seems completely effortless to her, causing her no strain or discomfort. She simply cannot control her aim with a deviation larger than somewhere around the size of a large city and requires satellite guidance unless she is unloading something RIGHT on top of herself, like Diabolic Emission.

Unfortunately Diabolic Emission seems to be the only spell she has that's intended for up close use.
In the opening of StrikerS, while aiming to help put out a fire with an ice/snow spell, she accidentally froze a spaceport.  Serious overpowering there.
