uncle no, his sisters aren't that much older than him and their oldest children are teenagers. but as cousins it can work that way for sure, he'd probably feel like your guy is more like a brother anyway like you said. he'd be totally welcome to crash on adam's couch until he got himself sorted out so i love how this sounds! adam can sometimes get himself into trouble but he's not the kind to reach out, he has some issues with his parents but if your guy's not conservative leaning (i don't mean politicallly, just in morals) it'd be a relief to him especially as your guy got older
