By the time a facility had the infrastructure, resources, designs and plans in hand it would likepy be 2023, if not the year after. No already existing manufacturer is going to change their fab around to accommodate new manufacturing processes that aren't that lucrative.

A typical chip fab can take 1-1.5 years to start up from design to licensing to construction to production under normal circumstances. The tools used in the line at wafer fabs themselves are in short supply, even used (I work in the semiconductor industry, I know the shortage exists because we have entities down waiting for parts for over a year now).

By the time a site got product moving, supply would normalize from the East and card manufacturers would immediately go to the cheaper components again.
