It doesn't matter if you're talking about a J-20A, J-20B, J-20C or a J-20D-thru-Z, unless those other post-J-20A aircraft are completely new and differently designed aircraft than they will never be stealthier than the F-35!
Remember, Stealth isn't something that you can simply add to an existing aircraft - you have to design it from the start.
And even if you could "add stealth" (or more precisely reduce RCS) on further J-20 variants like for example a J-20C then how would you compare it against improved F-35s? You are aware that the F-35 will also receive lots of improvements during its lifetime (probably even more than the J-20), no?
If you want to compare the "stealth level" of a tentative J-20C than you should probably "try" to compare it with an also tentative F-35D (or something along those lines)...
You can change the stealth attributes of an aircraft if you are prepared to bear the weight penalty of extra RAM. The Block 3 Super Hornet has apparently improved clean stealth by 10% with more/better applied RAM. You can go much higher than that if you are prepared to take ton hits on weight, the J-20 will eventually have more powerful engines and its prime role is as a long range stalking interceptor so they maybe prepared to take future hits in weight for that stealth purpose.
