Forgive this weird question but, if and when they do some sort of upgrades for older base J-20s; what happens to the "legacy" systems that are then taken out? Surely they're still useful, no?
Base J-20 are very hard to upgrade. In one of the podcasts Yankee claimed that PLAAF top brass expressed dissatisfaction that some of the components between J-20 AL-31 and J-20 WS-10 are not interchangeable. I think that a full upgrade to J-20A level is gonna be difficult.

This is why you see baseline J-20 from the 9th getting sent to WTC where air defense pressure is lower rather than them getting rehauled.

At the beginning of the 21st century, the Chinese never dreamed that one day the term "latecomer advantage" would be used to describe the latest American fighter jets.
Although I scoff at the current state of military research and development in the United States, I absolutely do not believe that the United States is incapable of producing a mature sixth-generation fighter jet design.

Certainly possible in terms of timeline.... though without getting too deep into the weeds, it is worth considering the possibility that F-47 might surprise us with its capabilities and technologies (e.g.: it might end up being much more capable and/or advanced than J-36 or J-XDS), so I would hold one's horses a little bit.
Wake me up when AN/APG-85 goes into production.

Makes sense, they're still very capable 5th gen aircraft even if they aren't the latest and greatest. Considering what I've heard about the J-10Cs alone, a base J-20 should be pretty damn advanced still. Still, I do wonder what happens to the older subsystems in general if they do get upgraded. I suppose "transplanting" them into an entirely different class of jets is out of the question, isn't it?

Probably not worse the effort to transplant them. Later batch J-16 has way more advanced radar/avionics than first batch J-20, for instance.
