Honestly I doubt they really add anything, but man a Zamperla Hawk would be a great successor for that spot.
A Zamperla Hawk would be a perfect replacement, because now, KD no longer has an inverting flat ride. They seem to be have maintenance issues themselves though, with the last new model being built in 2018 I believe (although Zamperla still does offer the model).
Last off season there were rumors of Meteor's demise at Dorney, only to find the rumors to be untrue. I did finally get to ride Meteor for the first time last summer, and it was way better than I expected. The 3 across per row seating was unusual, but it in addition to some fun forces, it was a surprisingly social ride experience. The queue on that day was full, and it was a good mix of families, teenagers, and enthusiasts. The three-across meant couples had to sit with a third person, and larger groups were split up even between both arms. Before the ride even started people were interacting with the other arm, and it was just a great time. I recognize not every ride cycle is like that, but I wasn't anticipating the social excitement. On berserker, you could kind of interact with people in front of you (most of my times my interactions meant avoiding someone who looked sick) but the high walls between rows made that difficult.
I could be wrong, but I also think Aero 360 at Kennywood had parts rebuilt or remotely within the last 2 years, as that was one of the earliest Hawks to be built. Maybe there's still hope for a new one to pop up, at a place like KD.
The other two options, apart from a Zamperla Hawk would be an Air Race or a Nebulaz. Like the hawk, both have enjoyable ride cycles for off-ride folks, which is perfect for the very first ride you walk past in the park. They also have the potential to have great lighting packages too, which would be a must for international street. An Air Race would also fill the void of an introverting flat ride, although the plot of land would be larger than Berserker's or a Hawk's plot (not impossible though, given the open area, just would require more pathway work. Nebulaz have proven to be very popular recently too, although I'm still holding out for one in Old Virginia, (name Virginia Reel) to give some life to a beautiful but neglected part of the park. Perhaps replacing the old Go Karts plot of land and open up a better plaza towards Grizzly, or even place it behind Dogwood's Grill, overlooking the rapids lake maybe replacing the current bathrooms. That corner would finally have a ride open during the winter months, and bring more foot traffic to Dogwood's Grill and Parched Pig.
