Is the chip in this bulk order (Atmega644p-20PU) compatible with this board? As I have limited electro knowledge I can't judge.
You will need to change the crystal to 20MHz. Otherwise you just swap the MCUs and flash Mega644 and you're good to go.
You don't need to change the crystal. It will work with 16MHz just fine.
