I don't think that this would really solve the problem with Nidalee. You have to consider what her weaknesses are, and whether this is truly enough to call her a healthy champion. Currently, her primary weakness is lack of engage. She has no CC, which is quite a large weakness. But it's not unique. There are other champions in the game who have zero CC aswell. So let's compare perspectively. Corki is currently a strong champion who does not possess any CC. He's still descent because he has large burst potential coupled with good mobility and poke. Ezreal, another who still quite descent, but even though lacking CC is still really strong because he has a lot of damage coupled with his blink ability and poke. Katarina has no CC, but has the mobility to jump in and has massive damage. Mordekaiser has no CC or mobility, which is why he isn't played as commonly or seen to be as strong.
Now, a lot of these champions have no CC, and apparently "lack engage", but they don't. They can get onto their targets and deal high amounts of damage. We come to Nidalee, who is similar to some of these champions, but also has good ranked poke and sustain. She also has better potential to stick to targets than a lot of other champions listed here.
