Moving the ball back in your stance wont help much. Most of the time your hands will just flip and you'll loose inside swing arc.
Also strengthening the grip will help a bit more, because it does promote an inside to out swing path, but it also forces the clubface to be more open as well, so its kinda counter productive. Note that is just a general tendency, not law, some players can hit pull cuts with a strong grip, so its individually based.
If you want to hit a snap hook, or a big hook, speed up your arms in the downswing with out speeding up your body. Really focus on pushing the ball right. It sounds counter productive to think right to hit it left. Then all you need to do is just control the clubface to get how much curve you want. If you want to really hook it, close the clubface a bit and really swing to the right. The goal is to get a big degree of separation between the clubface and swing path to produce a hook spin.
