Wordpress migration

I've been updating the wp2drupal module and wanted to make the changes available to the greater audience via d.o. But my changes mark at least the fourth developer who's worked on it - it was originally created by Borek Bernard, then updated by someone by the name of teodorani (who used to own teodorani.com but which is no longer working), and then partially upgraded to D6 by DenRaf. I've previously made some fixes so it would at least run, but I've started cleaning it up some and adding extra features, like GlobalRedirect support, support for both categories and free tagging..

So the question is, should I start a new project for this or try rewriting it to be based off one of the generic data migration modules: either Migrate (D6 only) or Migrator (D5 only, seems to be stalled).

Thoughts?

Thanks.
