Yorick reworked abilities, could it be this simple?

Yorick could have his abilities changed so that after his cooldown timers are up, he spawns the appropriate ghoul to act like elise's spiderlings. The active cast would cause the ghouls to attack in also the appropriate way. This would allow Yorick to have bursts of power and a weakness when all of his ghouls are down.

This could be implemented so easily and wouldn't entirely change his identity, please upvote this!
