Your problem (well, one of them!) is going to be with getting
elaboration right.

Then there's differences between the runtimes expected by generated
code.

For the elaboration problem, do you have enough 3.14 artefacts to
allow you to run the 3.14 binder? You could maybe make a library out
of the 3.14 code (+ 3.14 runtime)?

Not sure how much reliance I'd want to place on the result.
