Fix Collision of Jumping On Floating Player

My player is a spirit and floats in the air, in order to give this floating feel I increased the height of my collider so it collides with the floor lower. The only problem I have with this is when I try to jump onto a higher surface, the extended collider then collides on the side where the sprite isn't at. Is there a way for me to decrease the height of my collider while jumping? Or maybe a better way to give this floating effect without the worry of the collider? (This is all as a 2D Platformer)
