Can you make it so stone picks mine faster? I dont have alot of time to play. It should be like 10% slower than iron, or if you cant make them like iron
The point of the game is that you have to spend time getting these resources. That's why stone pickaxes are slow, so that you are actually rewarded when you find better materials. So no, they should not be faster.
Maybe just use hacks. Or play on creative, if it's that much of a hassle to you.
