It all depends of the final html output structure and what limitation we have to work with.

Basically we can use positioning to move the ads to the desired place. If we encounter a problem with the page length, we could add a JS class to handle it.

I think that the bast way is to create a JS class that enhances the sidebar and give it a collapsible option. Users will have to manually add the javascript code to their user space, or use greasemonkey/firebug/browser snippet to make the class work.
