" F-22 definitely not (platform wise only, there's 2 decade tech gap)." ----> Can you please elaborate on this?F-35 probably... F-22 definitely not (platform wise only, there's 2 decade tech gap).
Mark1 doesn't have side-bays, TVC or hidden engine nozzles like F-22. Edge alignment is also imperfect, owing to attempt of drag reduction.... Mark2 will be technically 6th gen, so again doesn't compare fairly.
I heard they tried doing that while testing all sorts of ballistic missile countermeasures for realistic simulation. We have ever don't that actually (assuming it's true, what I heard).
