Honestly only having two body types is the lazy part, no matter what the two types are. The best solution would be a variety of heights, weights, shoulder, waist, and hip sliders with boobs and butts and whatever else as add ons to the body shape. That should cover everyone as long as there is plenty of range on each option.
Unless everyone is in armor, in which case two or three gender neuteal body types are fine because boobs and butts won’t be noticeable through armor anyway. Height is pretty much all that is different if everyone in the armor is in decent shape and the armor is made to fit a range of people.
