I was curious if they could be swapped. Let's say a few years down the road I find a set of comfort seats on ebay, can I swap them out similar to how you could in an e53?

Also, are the headrests changeable? I have sport seats but really like the comfort headrest because I feel like I have to lean my head way back to get to the head rest. Ideally I could just pop a comfort headrest on a sport seat that matched leather, that would be the best of both worlds for me.
