Random define r4 and r5 question

Im bored and Curious. I have an r4 and would like an r5 only because of the front piece that includes the side vents, power button,front door, etc. Anyone know if it is possible to swap the one on my r4 with that of the r5?

I don't believe there is from the reviews, unless you want to get into chassis modding. Which I am no expert in.
