To be fair, I'd argue that if those two are too similar then the same case could be made for most every USN/MC F4U-1A since there's not a tremendous amount of difference between the tricolor aircraft aside from how they're weathered (which is why I prefer skinning ones that make the Millennium Falcon look like it's fresh off the showroom floor).
Here is what is going to happen. Those skins who closely resemble each other could end up being removed from the game, if the slots get full for skins.
So, we
encourage skinners to try and not make skins which closely resemble each other in an effort to get as much variety as possible in the limited slots we have available.
