This is doable, it is impossible right now, but given enough time, quite probable that one could take an old design, and move it to a new PDK and have it automatically adjusted to meet the same timing and power constraints. If only one could take the GDSII for an old process node and just make it smaller. Maybe someone will make a model that does that, just contracts images of polygons. :) It would require not only the tooling but also past test runs of all of the verification passes to confirm that the new design doesn't have a flaw.
