Not that easy. You'd have to use special tools to rewrite flash memory to change the serial number, then DFU and restore iOS on the grafted device. The device enters DFU mode if you replace the main flash memory, and Apple activation servers will refuse to activate this device because the device S/N mismatches with the IMEI written into the baseband. So low level reprogramming is required.
