I don't know of any addon that would allow you to make your own changes to the Nav bar. I've seen addons that added items to the Nav bar and the Durkin Impact Suite has a module that changes the the standard text based Nav bar to an icon style bar.

It would require a custom addon to do it. The cost would be dependent on what you needed done. Contact me offline if you'd like to discuss it.
