Rear cage

Well I bought a blue 900 4 rzr. Pick it up this week, I was wanting to take the rear section off that is about 3 and a half ft that covers the bed and redo that part where my cooler fits in it better and chop th middle and rear section 4 inch. What do you guys think? Can it be done and will cooler be accessible? And still use say the emp front full windshield .
