Can we trade a bigger Nidalee Q hitbox for reverse execute damage?

Yes, I know I'm talking about making Nid's spear hitbox bigger but hear me out. This is a buff and a nerf.

Her hitbox is tiny. I'm pretty sure it's tied with Corki's ult for the smallest skillshot in the game. For such an important part of her kit it is frustratingly small, to the point where your aim can be close to perfect and it'll just seem to go straight through the person. Corki's ult at least has the virtue of being an AoE. Really, the hitbox needs to be a little bigger. Not as big as the old hitbox, but bigger than it is now.

Not a lot of people want her old playstyle back, though; nor should they. Buffing the hit box and leaving it at that would bring that back, and she's already in a strong state. Clearly she needs a trade-off. Her playstyle is to soften someone up from a distance and then go in for the kill, so her human form Q can reflect that a bit more. It could do less damage the less health the enemy has - a reverse execute like Elise's human form Q. With enough of a damage curve it'd make her Q effective only when hitting a full health target. She can't use it to constantly poke the same person.
