Yorick has trouble fighting outside of lane right?

I'm sure this has been suggested by someone else before but they should let yorick use his wall as a ghoul grave spawner by killing it himself with a recast of his w, every level you put on the wall past level 2 will increase the ghoul count by 1, so it would be

1/1/2/3/4

that would make it scale with levels and help him fight outside of the lanes, alternatively they could make it so that it spawns ghouls equal to the amount of hits it has left for hp so that fast attacking enemies can possibly kill the ghouls before they spawn.

Thoughts? This is of course possibly with the idea that they'll be buffed to receive a portion of his protections too not just his ad and hp, maybe make the hp scale with ap a bit? I dunno I just thought it was an idea I never saw a thread for.
