SAVED GAME HELP!!

I bought Borderlands 2 on ebay and have been playing it for a couple months now, maxed out characters, lots of weapons etc. I bought and downloaded some DLC for it, but I have subsequently found out that the version of Borderlands 2 I bought (international version??) is not compatible with the Australian DLC I have bought. I have been told by Playstation Support that the only way to rectify this is to buy an Australian version of the game, which I have. Now I have no problem with the DLC, but my saved games from the other version are obviously not compatible with the Australian version. I really would prefer not to have to start the game all over again just to play DLC, so basically my question is: Can my previous save game files be edited so they will work with my new version of Borderlands 2??

Any help would be MUCH appreciated.

Thanks in advance!

I guess alternatively, where could i download other peoples save files that would be compatible? Or would I have to modify them to work with my game aswell? Sorry for the noob questions..
