Yes, but only if you are willing to write C code that runs inside the
database server. That way, you can do anything (and cause arbitrary
damage).

The big challenge here would be to do the swap in a safe way. How do
you intend to guarantee that the foreign keys are valid without a table
scan? How do you handle concurrent data modifications?
