Answer: 
It's not possible to work on a function like this, because the Unlock-Screen is a part of the *Springboard.app*. You can't change something in another app, **this is not possible.**
You would need to jailbreak the phones for changing something in the Springboard.app.
No, no matter what your reason might be, Apple won't allow such an App because of various reasons (it could break any time due to API changes etc)
