Delude, the skin must be precisely matched with the original skin dimension. So, no, it is not possible to enlarge the keyboard size without changing the source code.
If you meant to enlarge the button size, well, I tried to maximize it as big as possible. As you can see in my skin, it has 2 pixels distance between buttons.
I can make it to 1 pixel, but it will not look nice ... too densed and cant see the drop shadow
