I have verified that adding a 4KN drive to a unit that previously contained all 512N or 512e drives works fine. I don't know about replacing one. But the partitions actually do appear 4K aligned in my system, so I'm not sure why fdisk thought they weren't on my system or yours.
Can you post the results of fdisk -l ?
