2015 polaris sportsman etx engine swap

I would be interested in taking the engine out is my 2015 Polaris sportsman etx and put the engine of a 2015 Polaris sportsman 570 in its place. So my questions are:
1- is it possible?
2- would I need to replace more that just the engine?
3- if possible and done correctly would it cause any problems?
4- has anyone ever heard of doing anything like this and how did it go?
