Dragon Age Inquisition: reusing my custom character

There technically no real way to do this at the moment. You would have had to have an earlier save, but I think you mean different class same facial features. You could do this in Origins using a mod but one doesn't exist for Inquisition. 

I would like to reuse my current character too... I do hope we can load the "face" of previous ones in a new game, just to live again the story with "that" character we loved, but making different choices.

If you want the same class (rogue, mage, warrir) then save the game as soon as you can after creating that toon, then COPY the saves folder to a safe location. When you want to replay that toon, swap that saves folder with the current one.

It wolud be like reload an old save of the same character, am I right?

Instead, is there any file in which we can only load the "face", not the "moment"?
