For me the real game changer would be having AI in your BVR AAM/BVR SAM so that it effectively has a Mk.2 Eyeball and can actively distinguish its target from physical and electronic countermeasures. It would also be able to anticipate and counter manoeuvring by the target aircraft manned or unmanned to increase the probability of a kill. Granted it relies on politicians allowing BVR engagement in the ROE in any future conflict.
