Recreating accurate historical minds entails recreating accurate history, complete with traumatized and anti-social individuals. We should be able to 'repair' and integrate them into future posthuman galactic culture after they are no longer constrained to historical accuracy (ie, after death), but not so much before. There may be some leeway, but each person's history is entwined with the global history. You can't really change too much without changing everything and thus getting largely different people.
