Why not keep just Lawrence on the front, put Smith's face as the spine image, then make a cover for Bad Boys II where Smith is on the front and Lawrence's face is the spine image? That seems like the easy way out.
Maybe move the title text up a bit on the front and/or make it bigger and/or add "A Michael Bay Film" to fill in that white space? Making it a bit bigger seems like a good possibility, since right now Martin Lawrence is over-powering it so much. Maybe you could even go so far as to see how it looks HUGE so that a little bit of the text is actually behind Martin Lawrence's head?
