An interesting idea, however the general idea behind the subconscious mind is that it simply makes decisions based on input data, much like a computer would. It didn't author or edit itself, it has evolved through Evolution like everything else has. All the conscious mind has evolved is self-awareness, with an illusion of choice being passed on from the subconscious.
And no, I don't see how we choose what goes into our brains. We experience things through our senses, it has nothing to do with choice. One idea I've heard discussed is that the subconscious is like an airplane's black box; constantly recording everything we hear and see. Even if we didn't notice something at the time consciously, the subconscious has a record of it, and you can "remember" at some point in the future. Feelings of deja-vu are linked to this idea; you see something consciously that you had only previously seen subconsciously.
To summarize, we are the summation of our input data, and all our subconscious mind does is make decisions based on that and whatever thinking processes it uses.
