Change clock position on lock screen?

Is there any way that anyone knows of to change the position of the lock screen clock. By default it is in the bottom left of the screen. The reason I ask is because I'm using a custom image, a family photo, where the current position of the clock is covering one of my boys face (much to his annoyance and mine). To be able to move the clock, to say the top left corner would be so much better. Any...
