io-file first and the modeldb file

Up until now I've been editing with a mod folder, although now it seems I will need to use the io-filefirst method to get my changes to the modeldb file to work in-game.

Is it possible for me to combine the filefirst method with my mod folder by just adding the io-filefirst command to the top of the batch file, or do I need to move all the edited files from the mod folder into their original positions in the main M2TW data files?

Also, would this code work for adding textures to Sudanese Javs for the Normans?

EDIT: I've transfered all the files and got the io-filefirst working, now I'll have a crack at the modeldb...
