Every one of the six scores encompass so many disparate functions that we really shouldn't use "real life" to say what some of those functions should or shouldn't be included. After all... Dexterity covers physical agility *and* manual dexterity, and we can find all kinds of people for whom they could do gymnastics but couldn't play the piano, or could do card tricks but couldn't stand on one foot for more than a few seconds. But any one of them might have a high DEX. We just have to accept that for the game they get to have both physical and manual agility (unless we're willing to go the 2E Skills & Powers route by splitting each ability score into two pieces.)
So that being said... if WIS does in fact have way too many saving throws attributed to it, and both INT and CHA are being underserved... moving something like Willpower to CHA in order to give that ability a bit more oomph for what it can do... I think for the game is a net positive.
