4.2 Lockscreen - How I think it should work

When you press the power button on your phone, I think you should be greeted by the full size widget:


You can see everything and swipe between screens without needing to touch the precise edges.

If you need to unlock your phone, tap the lock and you get the original lockscreen:


Basically, it's just reversing the process. I think it makes the lockscreen widgets more useful and easier to navigate.

The only disadvantage is that one more click/tap is required to unlock the device.

Anyone know if it is possible to implement this?
