What you need to do is to union only those parts of the objects that do not
overlap. So you can first remove the overlap from each part.
This is only a sketch. The rotates and transforms have to be duplicated in
the relevant locations. As written it would probably create a non-manifold
surface where the two touch; you should probably scale down or move the
subtracted objects so that the union ends up overlapping the the resulting
objects by a tiny amount. In creating "ObjectXWithoutHoles" you could
simplify it further; in some cases a bounding cube would be good enough.
