I have just picked up a new R2 Sensorscope with a better sticker, but now it's arrived I can see that the silver dome is not quite as nice as my old one.

So I thought I could swap the heads over, but upon removing them one is made of a green plastic, and the other one is white plastic (under the silver, you obviously can't see this when it's fitted.) One of them has a Hong Kong COO, the other has no COO.
I'm aware that these days people are very particular about having the right factory weapons with the right COO figures, but I was wondering if anyone knows whether there are any differences between the R2-D2 heads, I know that C-3PO and the Death Star Droid have all kinds of different plastic colours under their metallic layer, but are all R2-D2 heads one and the same or not? Will people be after me with a pitchfork if I swap them over!?
