I believe that the biggest obstacle to improved performance will be tuning, although the Predator flash tuner is now available. The engine hardware is not going to be a problem, since there are parts that were developed for the 5.7 and 6.1 Hemis. I would like to see Chrysler switch to a Mass Airflow system to allow a little more freedom in modding these cars without having to worry about getting the air/fuel ratio too far out of the normal operating range. I doubt that Chrysler would make that change, though, they have used Speed Density systems for as long as they have used Electronic Fuel Injection.
