Idea concept for Aatrox rework (overall kit)

Had a couple ideas on making Aatrox a more fun and variable champion.

Passive: Same passive as it is now.

Q: If the Q lands and knocks up an enemy champion, he can cast it once more (within 1/1.25/1.5/1.75/2 seconds) but instead of knocking up the enemy champion again he slows (for 1/1.25/1.5/1.75/2 seconds) all enemy champions that was hit with his second jump.

W: Same as it is now but every third hit on the same target increases the effects of that third hit. (For example if Aatrox attacks garen, on his third hit he will heal/deal the same as he normally would, but on the next third hit the effect increases by 15% -rough estimate- and the next third hit would increases again, etc).

E: Same as it is now but marks the enemy champion(s). If Aatrox lands a third hit, it will consume the mark; with his heal toggle on W, he heals 5% of the enemy's max health, or if he's on damage toggle, he will deal an extra 5% damage of the enemy's max health as magic damage.

R: In my opinion I like his ult the way it is. But to make this work with his overall kit I want to add the concept of : While ulted, while attacking a slowed enemy champion, Aatrox reduces his cooldown on his passive per auto attack (reduces 0.5 seconds).

This is just something I thought about while bored, feel free to criticize!!
