Do you think this fanfiction sounds interesting?

It'd be a Percy Jackson story. I was just thinking, when I was re-reading The Battle of The Labyrinth, what if the half-blood Luke's men found wandering around the Labyrinth wasn't Ethan? What if it was Nico? What if Luke convinced Nico to join Kronos's cause so that he could get his sister back? Tell me what you think.
