The Battle of Hogwarts.

The professors create the large spell shield, activate the stone soldiers and the Professors/Order of the Phoenix are then teleported away. In their place, the Hogwarts students receive these guys from the MCU with their standard equipment:

Cap (no hammer)
Spiderman
Falcon
Winter Soldier
Black Widow
Scarlet Witch
Black Panther
Nick Fury
Vulture
Red Skull with disintegrator gun

Let's say technology works in the HP universe. Most recent incarnations. Does the outcome of the battle change? Does Hogwarts win easier or do they lose?
