If someone is willing to explain me how hosting a game works, I would be willing to host one in February-March.
You set up a set of rules and then you specify the length of a turn (a week IRL for a month in-game, for example). Afterwards, you just have fun.
I say this just to establish the context of Windjammer's question, but we've hosted several GoT games already (three based on the War of the Five Kings, one on Robert's Rebellion and one on Aegon's Conquest), all of which have managed an interesting degree of detail and complexity. It is not an easy task by any means, which is what Windjammer (well aware of the games we've played so far) is pointing out at.
If there really isn't anyone willing to host one I could in theory, but I say "a few weeks" because I am handling Alea Iacta Est and Forward?, and unless one of those (if not both) ends I cannot do something as irresponsible as hosting a third game (my head would explode).
I think Dkrol would make an excellent GM, he had attempted to host one before I came forward with "The Iron Throne".
While I'm flattered by the compliment from the master of GMing, I'm not in a place in my life to make such a committment. I'm moving to London for four months in a few weeks and simply won't have the time to host such a game. Maybe when I get back in May, but no way I could do it now.
