So, I just thought I would leave my 2 pennies here. There is an archetype that is compatible with staff magus called Eldrich Scion that makes magus charisma based and gives you a bloodline. If you go unchained monk there is an archetype called scaled fist that turns you from WIS based to CHA based, so say goodbye to MAD (or at least reduce it by quite a bit, you don't need INT and WIS and physical stats).
