One possible plot could be that the Gundam Wing pilots are transported to the Harry Potter world. They then use their advanced mecha skills and technology to help the wizards in Hogwarts fight against Voldemort and his Death Eaters. The AC element might be incorporated as a new form of magic - mecha hybrid that gives them an edge in the battles. For example, they could use the AC technology to enhance the broomsticks or create new magical - mechanical weapons.
In a 'harry potter gundam wing ac crossover fanfiction', the story could start with a strange magical accident that links the two universes. The characters from both worlds start to interact. Harry Potter could be interested in the Gundam technology and try to learn how it works. The Gundam Wing characters, on the other hand, could be fascinated by magic. The AC part could be a key to unlocking a new power source that combines magic and technology, which they need to use to defeat an emerging evil that is a threat to both universes.
