As someone who acquired this skin after the fact, I agree that there should be an alternative way of getting this unlocked, even if it's simply paid dlc for one skin. Because it was a royal pain in the posterior for me to get it and it actually was just all luck in my case. I feel for anyone like myself that felt their game was doomed to be incomplete because of one skin I thought I couldn't get my hands on. I still kind of feel this way over the different pre-order jeep and copter skins.
If they want to keep it feeling special, make the exclusivity an achievement instead but make the skins themselves something everyone can pay for.
