China will not just use J20 against F22. first China will not send J20 to attack the US bases (at least not at the start), but the US may send F22 to attack China first for the purpose of helping defending TW, which means, China will be on defense on its land, therefore, the first detection of F22 will not be by J20, but by China's land based (or sea based) meter wave length radar, therefore the RCS at this point is not that important, China will know the space location of the F22, and how many of them, and where they are going. secondly, China can send fighter drones (FH-97A) 20 40 km in front J20 fighters, sure F 22 may shoot them down, but first it will waste the limited number of AIM 120 and will expose itself to J20, and let J20 lock it and fire PL15 to it.
in summary, J20 has no chance to fight F22 near the US base, same is true, F 22 has no guarantee can fight J20 near China
