Yes,it would be possible,you could either solder wires directly to the fpc cable,but that would require
extreme skill because of the amount of traces in that small cable.The other,easier way,would be to desolder the whole connector off the motherboard,and solder wires from the connector to the motherboard.Still hard,but easier than the other way,and not as risky.
And yes,it would be possible to solder the touch screen cables,just use PvP's tutorial
