I believe there is an intention to re-design the parsing stuff at some
time in the future to make the parse tree more easily accessible and
manipulable, so maybe something like this will be possible one day.

There's always going to be more to doing such a translation than just
token-to-token mappings -- otherwise it would be possible to turn Java
into Python with a few simple string substitutions. :-)

Yep, that's the really hard part!
