We can't backfill F-22s. That production line has been shut down. The modern F-16 equivalent is the F-35.
Now, the hang up for Poland is that the Migs and Sukhois don't require nice perfectly tended airfields because Russian doctrine was always designed around use of airfields tended to by a workforce inured to work. So, the Migs/Sukhois are less susceptible to FOD (foreign objects debris) than our very Ferrari-like American and Euro jets.
It was a solution to a technical problem somewhat like the Americans design a pen cable of writing in zero G and the Russians use pencils. In this case the technical problem was that Russians (and TBF conscripts in general) are lazy and don't want to sweep airfields for stones and other junk.
