Ideas for the Maokai update in the Vanguard update

Hi Readers! I thought about the Maokai update in the Vanguard update. Most of my ideas are just showing a possibility, while others are reworked mechanics/Abilitys. Its just a list, dont expect much text.

1. Let other Abilitys interact with his passive instaed fo pure AAs. Example: You gain life depending on his stacks and how many people he hits with his Q, Minions are 25% worth of a champ.
2. Champs hit by his sapling are marked and Maokai kann W over a increased range to them. The normal range for his W is reduced.
3. Saplings block Skillshots and can get hit by targeted abilitys like AA or Annie Q. They cant die, but getting slowed.
4. Champions hit by Q giving him 2x or 1.5x the amount of stacks when using an ability.
5. Probably my best idea: When R is activated he no longer gets dmg reduction, but gets shields, when an enemy near him casts an ability. These shields are magic or normal shields, depending on the enemy dmg type (like Camille Passive). His allys in his R are getting dmg reduction depending on how much shields he gets. The longer his R is activated --> more dmg reduction.
6. Units, who are getting hit by the skillshot of his Q (not the circle around him) are beeing prioritized, by Sapling in a 350 range.
