It would be a considerable amount of work to make it a runtime thing.
Ten years ago, maybe it would be worth the effort perhaps, but I'd
suggest just letting 32-bit slowly die instead of doing dramatic overhauls
that will no doubt introduce a bunch of regressions in code that's been
notoriously awful to debug issues in during the past.
