Mini-Rework for Yorick (idea)

I've had this idea spinning around my head for a while.

The main problem with Yoricks kit is that his harass/poke is also his sustain skill (E) making him toxic by default. So my proposition is to mix his Q and E up a bit.

New Q: Omen of Famine > ACTIVE: Yorick's next basic attack within 10 seconds deals bonus physical damage and and heals himself for X% (scaling with ability rank) of the damage done. > > Omen of Famine resets Yorick's autoattack timer. > > UNHOLY COVENANT: Omen of Famine summons a ravenous ghoul that heals Yorick for 17.5% AD on each of its basic attacks, doubled to 35% AD against enemy champions.

New E: Omen of War > ACTIVE: Yorick deals physical damage to the target enemy and marks them with War . Enemies that are marked are prioritized by your ghouls and take X% more damage from them. > > UNHOLY COVENANT: Omen of War summons a spectral ghoul with bonus attack damage and movement speed. While active, Yorick is Ghost ghosted and gains the ghoul's bonus movement speed.

With these two changes Yorick has to decide to invest in either poke or sustain while leveling which allows for general buffs to Yoricks numbers (like making his W scale with AD again) and his new E would allow him to disengage and engage more easily. What do you guys think, would something like this work?
