Can you fix octaine’s head hit box and also Mirage’s

Octane’s head  hit box and adjust it, it is bigger than wattson’s hit box by 9,000 pixels and it is bigger than pathfinder by 2,000 pixels even tho octane is the size of wraith his hit of is about the same height and still octane’s hit box is 24,000 pixels bigger than wraith. Last but not least why is mirage hit box is about 141,000 pixels and caustic hit box is 150,000 pixels why is that that makes no sense.
