Quick Idea for Yorick!

I hear Riot has been workin on Yorick for 3 years now, and Although I'm sure yall already got a but of stuff ironed out, I had an idea!

What if every time Yorick last-hit a minion or a champion with an Auto-attack, he 'buried' them and a little grave popped up (With larger ones for champions and bigger creeps) and then his abilities interacted with those? Because, you know. He's a GRAVEDIGGER. I mean, it would make sense, right?

Like, he could summon ghouls from them, and like his ult could be to form like a zombie golem from all the ones he has summoned or something
