[Rework Concept] Yorick, The Gravedigger

So, Yorick has been sort of a weird champion. He has his place, an excellent toplane bully that can turn into a great tank later in the fight capable of bringing back the team's most dangerous champion when they die, but I think something is missing. Yorick was created to fill a certain space, and was portrayed as such in the days before his release. He was supposed to be THE minionmancer, at least in the sense of having minions. He has minions, but they are rather weak, don't have too much damage until you have all 3, and even then they only last a second or two due to the massive amounts of AoE damage dished out in modern teamfights. So I decided to try and come up with a Yorick minionmancer rework concept that would retain yorick's key characteristics and his primary role (Toplane bully lategame tank), but make his overall mechanics and play more interesting and themed.

So here we go!

Passive- Splendid Corpses: Whenever yorick kills a unit, he gains 3 stacks of "Splendid Corpses". His abilities use these stacks instead of mana. Champions kills give 3 times as many stacks. he begins the Game with 10 Stacks (One for each player :P). His summons have 35% of his stats (except Movement speed and attack speed, which are equivalent). Even crit strike.

Q- Omen of War- Yorick expends 2 Splendid Corpses to summon a raging ghoul filled with anger, this ghoul has 25 (+.05AD)% more more movement speed and attack speed than the other ghouls (This means 25% of 35% of Yoricks movement speed and attack speed in addition). and will attack nearby targets, prioritizing yorick's target. This ghoul lasts for 7 seconds, until killed by non-champion sources, or until it takes 3 auto attacks or single-target spell hits from a champion.

W- Omen of Pestilence- Yorick expends 2 Splendid Corpses to summon a sickly ghoul filled with disease, this ghoul will slow whoever it hits by 15(+.05 AP)%, prioritizing yorick's target. This ghoul lasts for 7 seconds, until it is killed by non-champion sources, or until it takes 2 auto attacks or single-target spell hits from a champion.

E- Omen of Famine- Yorick expends 2 Splendid Corpses to summon a starving ghoul, filled with hunger. This ghoul will heal both itself and yorick for the damage it deals. This ghoul lasts for 7 seconds, until killed by non-champion sources, or until it takes 3 autoattacks or single-target spell hits from a champion. If this ghoul kills a unit, it can take an additional hit from a champion before dieing (But no more than 4).

R- Omen of Death- Yorick expends half his Splendid Corpses to envelop himself or an ally with a Flesh Golem. While in this form, all of the targets stats are increased by 35%, and casting his other abilities instead gives the target the effects of his ghouls (the extra MS and attack speed, the Slow, and the lifesteal) with no cost to his Splendid Corpses. If the targeted unit dies, the Golem will sacrifice itself to reanimate them for up to 7 seconds. While reanimated, they will have all their original stats.

Let me know what you think! I really only came up with numbers to give a sense of what it might be like. To be honest I have no idea if this would be balanced or not!
