Possible with a mata mata. However, consider their size. You'd not only wind up with ]V[onsters to hold their own against nearly 3ft 35+ pounds turtles but, you're also looking at way oversized filtration requirements and aquarium size to keep up with the extremely caustic waste production of these turtles.
Another limiting factor is how to keep a mata mata properly fed with monster fish in the tank going after the food intended for the slow-feeding turtles.
