(I'm not an expert,i have limited knowledge on the subject) Much more likely is resistance to UV without changes in transmission route, so it survives longer in droplets. However there is a (tiny) chance of "recombination" with another airborne RNA virus that is "compatible", where two viruses share genetic material while infecting the same cell and the resulting hybrid is viable "airborne Ebola", however it would be sharing traits of both viruses.
