That could open a tremendously nasty can of worms. If my memory serves me correctly, the bottom cases between the 2.0 and the 2.4 models were different on some machines... so the screw holes moved ever-so-slightly on the logic board. You may run into issues with cables as well. The older fan style won't fit into the port on the newer boards. So on and so forth. I don't think the board can be swapped without swapping a lot of other components.
