Given that Ranger has a modest bustline as a seeming reference to the island being an afterthought (Ranger's pads jokes incoming), I kind of doubt it. Most of the other busty carriers in the USN have an equally busty contemporary in the IJN (Saratoga -> Akagi, Hornet -> Shoukaku, and Intrepid -> Amagi) so the USN contemporary to Houshou would probably not be too stacked.
