Lets suppose, hypothetically, I took a pack of grey wolves and exported them to Australia, then I crossed them with the dingoes present there, what effect would that have on the ecosystem? Dingoes by themselves can't hunt cats and other invasive species, like the Asian water buffalo destroying ecosystems there, but if we evolved dingoes to a more savage species by introducing predators who hunt cats/buffalo to their genepool, hypothetically they may be able to control those species.

Thoughts? Technically this doesn't count as introducing new species to Australia, as dingoes are already natives and they're the same species as wolves.
