I recently did a major update of the housing page at EQ2Traders and personally visited nearly every house type in Norrath.
The maps and textures used would work for a number of the houses since the 4-room is basically two 2-room acorns joined and the 3-room is a single acorn with three levels and no ramp at the door. The only layout that would require special work is the 7-room monster where the lower level of one acorn has three rooms. Of course that's the one with the balcony as well.
Not sure when I'll get around to mapping some of these places.
