Can Yorick's ghouls get a health buff?

For something that is such a large amount of his damage in teamfights, Yorick's ghouls really dont have a lot of staying power. They jump in on the target he hits with his E, get off maybe 1-2 attacks, then die instantly to whatever AoE is flying around the teamfight without anyone even intending to kill them. 90% of the time they die without anyone even trying to get rid of them.

It takes so much time to get 4 ghouls ready for a fight, and Yorick gets almost nothing for the graves he digs. You'd think that the ghouls would at least have enough health that they can stick around long enough to do something. It seems like every time I send the ghouls in, a Renekton uses Q and kills them all, or Syndra uses W or E and one shots them, or some other meaningless one-off ability is used and they all die in 2 seconds.

Can his ghouls get a health buff? Or at the very least get more health scaling from Yorick's items? They're so flimsy that they might as well not exist once the laning phase ends.
