Maybe- and you'd have competition in the Iron Islands for sure, in the form of the Harlaws- though do bear in mind, quite a few Greyjoys are now basically dead, and the house is a little in tatters.....though it could be recovered.

Otherwise, the Riverlands are available, and I'd highly recommend taking them- as well as Dorne and the North. 

TLDR, the plot has mainly revolved around the southern Kingdoms for now- with Aerys III, the son of the disinherrited Daneys Targaryen (twin brother of Aegon X, the dead King that this RP started with) emerging back onto the throne in a lieu period where it was effectiely a free-for-all, a war that emerges between House Tyrell and House Crakehall, as well as a revolt in the Stormlands. As of now, the Tyrells are the closest to the "loyalist" throne in King's Landing, with Lord Garland Tyrell being the current Hand of the King (though he's left that to someone else in his stead), and his uncle, Ser Willas being the last of the Kingsguards left. They have held the city off against an attack by the Westermen, with some assistance from a pair of Targaryen sisters and their dragons who have decided to leave the Seven Kingdoms for the Stepstones- though it's come at the cost of several thousand soldiers and civilians, and Garland Tyrell getting wounded to merely get into the city. As of now, Garland is quietly leaving the capital for who knows where, and Aerys is currently unconscious after a serious headwound- with trouble brewing beyond the Wall too....oh, and there's plenty of (implied) fucking and people getting brutally fucking stabbed. So yeah, it's pretty mad :P
