Yeah, as I said, you can reboot only something with a completed source. Like, when the novel gets a manga adaptation. It's not a rare sight when the artist has problems, and whole manga gets a reboot.
But Sato brothers have no completed script.
If rebooted, it will be a completely new story and a new artist. So what's a point?
I can't image HOTD without Shouji's art. Besides, HOTD's story is rather generic. Because it's survival, so it's better to start something new. Sadly, looks like no one understands how to make a good manga about zombies these days, so I'd rather let HOTD rest in peace than to watch it ruined someday.
HOTD was born by Sato brothers and will die together with them.
