I don't believe that either of those two actresses would be willing to do a scene like that. Actresses have a lot of clout in terms of their nudity, and top-billing actresses (Halle Berry) don't get forced into nudity like that. They have to be willing, which Halle was.
In fact, I saw her in an interview saying that she was making a "conscious effort" to get nude on screen because it did a lot for her self-esteem and in turn, her sex life. It was also a decision that her husband, Eric Benet, encouraged.
