Do you know any published paper focusing on feeding interactions (predation, competition, niche partitioning) between alien/invasive top predators originating from different areas when they co-occurr in a new area?
You may also want to have a look at papers dealing with biological invasions, intraguild predation, insect introduction for biological control.

Probably not quite what you're expecting, but, interesting nonetheless:
Article Linking Top-Down Forces to the Pleistocene Megafaunal Extinctions
Abstract:
Humans, in conjunction with natural top-down processes and through a sequence of cascading trophic interactions, may have contributed to the Pleistocene megafaunal extinctions. The arrival of the first humans, as hunters and scavengers, through top-down forcing, could have triggered a population collapse of large herbivores and their predators. We present evidence that the large mammalian herbivores of the North American Pleistocene were primarily predator limited and at low densities, and therefore highly susceptible to extinction when humans were added to the predator guild. Our empirical evidence comes from data on carnivore dental attrition, proboscidean age structure, life history, tusk growth rates, and stable isotopes from the fossil record. We suggest a research agenda for further testing of this hypothesis that will provide a more detailed comprehension of late Pleistocene megafaunal ecology, and thereby allow us to better understand and manage remaining megafauna.

There's quite a lot of literature on this combination (cats and foxes in Australia) and also foxes and dingo. This paper will get you into that literature.
