Whoa, whoa, whoa. My instincts tell me that just isn't going to fly by itself. You'd first have to bump up it's Int to 3, and even then I don't think I'd allow it. It's a Helm of Comprehend Languages and Read Magic, not a Helm of Helm of Comprehend Languages, Read Magic, Be Capable of Abstact Thought, and Gain Self-Awareness. Even familiars with their Int 6+ possess a mental mindset that are not built for such things.
