if giorno can make life, could he theoreticaly turn a door into ultimate lifeform kars? he is also a living thing

[chilly frigate]

he would need cells from kars himself to make a clone of him, like how he cloned coco jumbo

although we don't even know if he can make organisms that large, he's only created small animals in the story

the ultimate lifeform buff isn't a naturally occuring state either so at most he'd only be able to make a base pillar man
