Razer Blade 2014 and 2015 chasis question

I just bought a RB2015 (QHD+ / GTX970M / 16GB RAM) to replace my RB2014 (QHD+ / GTX870M / 8GB RAM), my only concern is that the 2015 one has some scratches on the chasis plus some minor wear on the edge of the palmrest.

My RB2014 is in perfect condition, so i was wondering... is it possible to swap motherboards between both systems?
