I don't think so. Nemesis took Ethan's eye as payment for him bringing respect to the minor gods. Ethan's death lead to the minor gods getting respect, as him going against Kronos gave Percy and Annabeth time to get Luke to kill himself. And Percy wished the gods be given respect by having cabins and thrones. Nemesis has no reason to seek vengeance against Percy.
