And if F-22s enter the merge, then USAF is doing it wrong or has mismanaged the engagement. That is supposed to be the last ditch option. F-22s manage the battlespace with less stealthy platforms providing the weaponry BVR. When things go awry only then does the Raptor swoop down from FL600+ and engage.
When we think about modern engagement scenarios, we MUST understand that airplane kinematics are not the primary ingoing strength. Management and manipulation of the airspace environment to remove (or surreptiously modify) command, control, communication and intelligence is a force multiplier of epic proportions. As noted above... just ask the Isreali's.
