That isn't how adaptation works. If Plasmodium could survive in other mosquitoes, it would do so already. It isn't limited to only one species, and scientists propose the extinction of all species that harbor this bacteria. Adapting to new environments is hard. Other mosquito species that feed on mammals have existed for millions of years. Whatever adaptations could have happened to allow the bacteria to survive in other vectors, have already happened. Bacteria don't have willpower; they're not going to tell themselves "Anopholes is dying out! Now we have to work really hard to colonize other mosquitoes!"
