Can You Swap lock buttons on CDMA to GSM iPhones?

I have two iPhones, one of which is a CDMA and the other being GSM. The GSM is white and the CDMA is black. The black one is completely destroyed, being the front and back are both completely shattered, no home button, the bottom part of the screen doesn't work, and the battery is bulged out. The lock button works fine, but on the GSM iPhone, the lock button, is well, iffy. It doesn't click, and is hard to press, but it does still work. Instead of paying for another lock button, could I just swap it out?
