Would midsize/jumbo grips help a hook?

If the ball starts straight I wouldn't think it could be out to in swing path and a closed face unless the aim was to the right.
Or the aim and swingpath are square but a strong grip
Or aim well right and an out to in swing with a 'rescue flip' at impact.
Or the weight too far back with little rotation
Or an in to in path
etc
etc

Whichever, if the ball is low left, the clubface must be closed at impact.
