Think of it like a gaming computer, you can have the greatest GPU in the world, but if you are running on a Pentium 3 there is simply no way you can play games on it. Vice versa, no amount of CPU horsepower can make up for a junk GPU. It is a system where the parts complement eachother.
The best image sensor in the world will not make up for bad optics, while the best optics in the world cannot make up for a bad sensor (unless shooting low resolution with a ton of light.. and even then...), the weakest link will always be where the problems show most.
As others have mentioned, if you can afford this, why not just buy a camera? It would be so much better quality. Or better yet, make a case like this for a phone that does have a good camera.
