Integration with book menu

Would it be possible to have the book navigation menu appear in the taxonomy_context menu where the book root page would be expected to appear, and the book pages' breadcrumbs to then be prefixed with the root's taxonomy_context breadcrumbs?

I managed a partial solution by getting the book root to show up in the hierarchy, and stay open while its children were navigated via the book module's menu block, but this involved some ugly php hacks which I have to update whenever I update taxonomy_context. The apprpriate breadcrumbs had to be hacked into the book module.
