Re: Umm... nope.
I roast coffee at home, and one of my suppliers regularly sends out cards with coffee-centric news. This isn't recent news. (And yes, my cuppa really is better than your cuppa.)
What is happening is a fungus is ravaging the coffee plantations, just like other fungi are killing bats, salamanders, banana plants, and all sorts of other things. The biologists suspect that the fungus has become prolific due to warming weather. (That, and monoculture.)
Can the domestic coffee plants be saved by the wild coffee plants? Same way that the domestic banana plants are saved by the wild varieties: they aren't. The domestic plants are replaced in agriculture by varieties that are resistant to the fungi.
