Not having it in my computer, without a grid overlay I don't know how much to the anti-clockwise it could rotate to make more horizontal the base "wedge" as it has become known, before compromising the body of the building. But it's great as it is, and just for the hell of it, I think I would rotate a little and clone in a bit of base to retain the weight there already is.
After all, perfectly parallel sides (seen from low positions) look as "wrong" as do space-travel, vanishing upper floors derived from super-wides.
This is mental stuff for winter, not for the heat of the day down in... Chuck, baby, back to rest.
