The Sands of Renewal prestige house (home_takish_) does look quite similar to the Buried Takish'Hiz dungeons. The first room looks like Takish Archives, which is the same layout as the final room in
Foundation of Knowledge. The adjacent room looks like Chamber of Chronicles on that same map. Unfortunately, those two rooms aren't adjacent in any other version of Buried Takish'Hiz. Some clever adjustments with Photoshop and/or sub-zonerects could be used, but no existing map will work as-is.
