Impossible. There is no way China will allow that- it would lead to a Cuba situation.

I can't see how this wouldn't favor Taiwan? All the US republicans would start screaming about WW3 etc, it would put major pressure on China. I'd say it would be ideal for Taiwan.

The discussion now seems to be, "How do we get the chips out of Taiwan so we can let it fall to authoritarianism with the least political fall out possible".
