You can do math all day, you can be exceedingly good at that math, you can use numbers and variables to express your point in a way which promotes you to be expert in your understanding of the process and the meaning behind the process; but until you actually do it, the equations are meaningless.
The truth is that you can crop in, but not nearly as much as you would think.
When you crop in, you're basically telling groups of pixels to act like individual pixels and they don't. Parts of the remaining resolution pixels will be overlapping into other pixels. It does not work like you think it does. I've tried it, and so has anyone else who owns a large megapixel camera like the Nikon D800e that I used this method on.
It doesn't work on any camera. It never did. It never will.
Now this doesn't mean that you can't see some progress toward your goal. But the 100% actual truth of the matter is that if you had a 35mm prime on a Nikon D800e and you took it off and put the same quality 70mm prime on the camera, then took a photo and before anything else you brought that picture to photoshop and cut 1/2 the resolution off it; then that image would ALWAYS be better than if you had used the 35mm image and cropped into it by a factor of 2. ALWAYS!
Some of you seem to think there's a way to overcome the logistics of optics. There isn't.
