I think I can work with you to prevent a catastrophe.  I've faced this
kind of situation before, and I've built the best tools in existence 
for coping with it.

I know from lots of previous experience with messy conversions (NUT,
Hercules, Roundup, groff, and a number of others) that these sorts of
halfway-out-of-band mechanisms are fragile and *never* work as well as
advertised.  The pain you think you are avoiding with them will come 
back redoubled.
