Sadly I'm not aware of one but it would be really, really, really cool if it existed.
nobilis and Amber are similar thematically and power-level wise, and Nobilis is one of my favorite game books ever made, and while they don't line up exactly you could almost certainly tweak them to fit, should you desire to do so.
Still, I have visions of a hradcover Lords of Lights RPG in my head and it is beautiful. The world it self is very cool, has a nice amount of depth, and the comb of sci-fi with hindu mythology is something that still hasn't really been repeated. And I'm sure you could run many fine campaigns in it without ever playing as the Gods themselves.
