[Spoilers Extended] What House/culture in ASOIAF would you want to see an “out of the normal” character from?

Reading through the series, the various Houses and cultures throughout the world seem to share a lot of characteristics both physically and temperamentally.

Of course there is depth to most of the POV characters and subtleties to everyone, but you have the stereotypes like Lannisters being beautiful and cocky or Starks being stern and humble. If you could write a character that it completely out of the normal for their house, what would you like to see?

A few I’d find interesting:

-An extravagant male Stark: You get used to seriousness of Ned or someone like Cregan, so how about a Stark man that dresses in jewels, crazy Wolf themed coats/armor, enjoys feasts , going South, and riding in tournaments.

-A politically minded Greyjoy: Despite being known for their naval prowess, I don’t think a single one has ever been named even Master of Ships. Imagine a Greyjoy who wanted to play the Game of Thrones in the Red Keep. A Tywin mixed with the reaver mentality at the Small Council table.

-A Targaryen High Septon: It’d interesting to see a story where a spare Targaryen Prince deliberately chooses the Faith, becomes High Septon, and sets up a rival court to his royal brother at the Sept of Baelor.

What are some of your outlandish character models?
