They can be. It is possible for those individual streams to be entire personalities, though I've only rarely touched that space, and only during peak experiences. I'm not sure yet how I can put that to practical use in ordinary, day-to-day life. In the version you have, the times when I usually have something like that arises is when I'm playing Go or when I'm making architectural decisions. I don't necessarily try to give voice to all of the threads, but rather, keep them in varying states of potentiality, while examining a single thread to check it's validity. It's not always necessary to render a thought stream into a voice until you need it. Kinda like lazy eval, I suppose. I've met people who are significantly more intelligent than I am, and I can usually tell, they are doing something similar with greater clarity. And I'm just barely hanging on to the ride, trying to keep up with them.
