a cool idea for jhins passive

i just want to start off saying that im a jhin main and i love his kit and thematic 100% and wouldn't change anything about and im not asking for a rework or anything. but thid idea just popped into my head like what if his passive tied into his teasers a bit more?

like his passive "beauty in death" would tie into the different elements we kind of see in his teasers zed=tree/nature vi=fire sona=smoke/wind garen=diamonds

now what if everytime you killed an enemy champion it would randomly spawn a buff in the place where the champion died that did different things?

tree: when you kill an enemy a tree will grow from their corpse and you and your teammates can walk under it and heal for x amount of hp.

fire: stays the same as his current passive.

smoke: when you kill an enemy champion a smoke screen will erupt from their corpse turning you and any allies standing in it invisable for x amount of time

diamond: when you kill an enemy champion standing near their corpse will give you a temporary sheild that absorbs x amount of damage.

thats really it. again im not asking for any actual changes to jhin its just a cool idea i thought of and wanted to share with people. thank you for your time and gl hf
