I do this quite often (ConTeXt -> LaTeX), so I am just writing my thoughts
about this. A general purpose translator from ConTeXt to LaTeX is VERY
difficult, because of the nature of both macro languages. However, it is
relatively simple to convert a subset of one to the other. Currently, I
write most of my papers in ConTeXt. For the final version of the paper,
most journals want LaTeX. I know my style of writing ConTeXt, and can
easily convert 95% percent of it to LaTeX using regular expressions (and
have been thinking of exploring gema in more detail:
http://gema.sourceforge.net/). It is easier to do the rest by hand rather
than writing a script that takes care of all the corner cases. Usually it
takes me around 2 hours to convert a (30-40 page) paper from ConTeXt to
LaTeX. Since this needs to be done only once every six months or so, I
have not spent too much time trying to optimize my approach. I think that
the same will be true for conversion from LaTeX to ConTeXt. However, I
would suggest that you start by writing some ConTeXt documents by hand,
before you automate the conversion. This way, you will know what you want
to achieve from a conversion script.
