I want to turn this:

Into this:

All the main features of the SP would be placed in the same place as the old Gameboy's guts. (Game slot in the same spot.. battery where it should be, volume and link port as they are on the GB)
Right now, I don't have anything to take apart and look at.. but, is this do-able?
I I know I'll have to rewire some stuff. And I don't know anything about that.
Anyone have anything that would help me?
..and my major hurdle, getting the SP buttons to work through the GB's button layout.
I doubt I can cut the circuit board at all. So I need another way to make it work.
..unless I can cut the circuit board. Info on that would be nice.
