Fred and George Weasley versus Anakin and Obi Wan....
The Weasley Twins versus Anakin and Obi Wan (AOTC version).
Anakin and Obi Wan have all their Jedi powers from AOTC and their Lightsabers.
The Weasley twins have their wands and all the following spells: Impedimenta, Expelliarmus, Levicorpus, Petrificus Totalus, Accio, Crucio, Ascendio, Reducto, Bombarda Maxima, Protego, Descendo, Imperius, Incarcerous, Sectumsempra. They also have a firebolt broom each, and the original Marauders map. No Avada Kedavra.
The fight is not necessarily to the death. Victory can be claimed by KOing the opposing team. It is in Hogwarts castle, and the Weasley twins cannot apparate. Obi Wan and Anakin have a rough map of Hogwarts, showing the basic layout of the castle.
The twins are in the Gryffindor common room and see the Jedi approaching.
Who wins?
