There are two brown earth wires from each window switch. Re arrange the wiring so that they are in two groups. All the wires from the same pin on each switch connected together, and the same for the other pin.
If 12V+ is applied to one of these groips and the other group earthed, all the windows will move together.
The problem that will arise, especially on a four door, is that the current draw will be excessive, and probably trip the cutout.
