Honestly i would feel more interested in a smaller house like Osgrey, Darry, Butterwell, Strong of Harrenhall, Caron of Night song. Something like that. Stark and Lannister are too overused with the exception of Arryn, but it gets boring when the MC is born already as the heir of the most powerful houses. I would probably end reading whatever you make but it would be great if at least you give some thoughts to my suggestion.
