I tried but keep running into a solid wall... haven't given up and have even played around with writing new versions but both mods are so big you would need a separate site and several staff to get anywhere... Couple this with that fact that phpBB 3.1 has code to support downloads and one nice gallery mod in development... you have to ask if all the effort is worth while... why reinvent the wheel....
It would probably makes more sense to work on some type of import script closer to the phpBB 3.1 release...
