Using older DD parts on a newer body or vice versa

I recently had my original Miku, so she has a spare pair of hands. I decided to use that pair on my newer DD f-3 SWS custom.

Here's how it looks:

But if you look closely, I can tell that there is a difference:

 

While this doesn't really bother me, I guess at least I can see what age does to a SWS DD. I have a DDS Mio Honda and she's aged pretty well, but I don't have newer flesh parts to compare the skin color. 

Feel free to share if you also swapped out parts within your newer and older dolls!
