absolutely yes, i even have a fic idea like this though i guess it's less like babytrapping and more like he xuan straightforwardly atticwifing shi wudu...i imagine he xuan getting shi wudu pregnant during blackwater arc instead of the whole 'shi qingxuan has to kill you or get an awful fate' thing. and yes it'd totally mess up shi wudu so badly, like he'd be allowed to go back to heaven but he's now pregnant with a supreme's child and everyone can tell but also he needs to stay strong to protect shi qingxuan it's all just too much for him. and then he needs to come back to black water's demon lair whenever he xuan demands it to check on the status of the pregnancy
