I doubt it. As far as I can see, it is the other way around, i.e., mappables (e.g., images) know about the colorbar they are connected. But I hope some other developers can confirm (or dispute) this. For this kind of work, you need to understand some of internals of matplotlib, and I recommend you to go through the matplotlib sources.
