Cost is extremely prohibitive, I've just Googled* F-16 costs which vary from $17m - $45m, F-18 $29m - $57m, Typhoon about £120m or ***8364;120m (easily confused
) maybe much less if we had the US buying power.
So worse case is 4:1 Typhoon to F-22, and the F-16/18s would be nearer 10:1.
I'll take the ten, please. Unless one of your aircraft can carry eleven long range AAMs.
But the JF-17s are even cheaper, mass produce them and throw them at your very expensive aircraft.
Ten launch per incoming threat, shoot four down, two will fall apart, that leaves four still (trying to) kicking your ass.
*as such these may require a pinch of salt, but I'm guessing not too dissimilar to real costs.
