Replacing Rear Camera with an iPhone 7 Camera?

I was curious to know if anyone has ever successfully replaced an iPhone 6s camera with a 7 camera, to get better quality photos. Is there a possible way to switch them out, and if the connections don’t fit perfectly, is there a way to actually change the connection piece? I’d like to test it out and see what happens. Any info would help! The only thing I like about the iPhone 7 is the camera- the other upgrades are very annoying, so under no circumstances will I get a 7.
