I'm just working on my comprehension of all these questions but I think that even if you wanted to, you just can't become hearing. If you are Deaf, or born deaf, you think in a different way. It's so clear in kids (yes, even CI stars) when you interact with them... Thoughts follow different paths. So I think you have nothing to worry about
The thing I do believe in (call me a dreamer) is being able to share our being part of Humanity. Differences are enrichments, because we are all part of a whole and we can share each other's knowledge. If both hearing and Deaf people would accept Sign Language as a patrimony of the whole Human Race and not only a "tool for who has a deficit" we would all gain soooo much... But times are maybe still not mature for this. Or maybe I just should sleep more at night, or my thoughts will become too strange
