Would taking this feat create an exception to the rule, or would the feat be limited by the rule to only the playable races? To give a more specific example of what I am wanting to do, I would like to take this feat to gain racial affects of Kitsune. I want to gain the favored class bonus for Sorcerers of +1/4 DC of enchantment spells. Would this be acceptable. Also, if taking this feat allows this, what else would it allow?
