That's an interesting choice, it doesn't encroach on Reed's scientific role (even though I don't think being a doctor would) and it lets her take point in the other aspect of the FF, exploration. I really like the idea, I just wonder how it would be implemented.
The more I think about it, the more I love this idea. It would fit with her personality, trying to learn the culture and language of other cultures and alien species to help foster relations with humans.
