The F/A-18 also was tested with a thrust vectoring system. In reality, a TVC system could be added to pretty much any 4th generation fighter. Would take some work to rig it up to the flight control systems of some planes, but with full FBW aircraft, it wouldn't be as bad since it would mostly just be adding new code to the control laws.
The Multi-Axis Thrust Vectoring (MATV) exhaust nozzle from the F-16 Vista for example, had two versions... One for GE F110 engines and one for P&W F100 engines. The nozzles could be retrofitted to any F110 or F100 engine, as long as the FBW system of the aircraft could be modified to accept the changes. Although, there is a minor weight penalty with a MATV nozzle, the increased agility is absurd.
Cost and fancier missiles, along with stealth, sorta kept the nozzle from appearing on production F-16 and F-15 aircraft.
Anyway I imagine if AC7 has any sort of modification system,
it probably would be similar to ACI. Because really, I see ACI as more or less a testbed for ideas to be featured in AC7. Would be nice if it has a somewhat in-depth customization system as others have said. It would be neat to have nearly GT or Forza levels of modding for the aircraft
