Let's mod Dead Rising 2 - Playboy bunny Lulu saves Katey. 

In the cutscene, Sullivan has the cheek to halt Lulu and put his hand on her breast.
This mod isn't bad, I do love playing as Lulu. There are downsides to the mod, due to the height difference Lulu's heels clip through the floor. Also, certain angles in both cutscene and gameplay will give her a crooked/hawk-like nose.
In game, it is possible to mod the voice so you have Rebeccas grunts but I would vote AGAINST this, it can cause an infinite loading screen when switching zones. The only way out of it is to close the game and restart it, resulting in a loss of progress if you haven't saved.
