Not to suggest that you completely rewrite your application but ...
I've solved this in the past by creating a lightweight view object that I use for my item nodes in the outline. The view object references the original, encapsulates a lot of the model->view translation (like constructing the node's display name), and -- most importantly -- it contains a parent pointer to the super-node that owns it in the outline. This allows me to easily traverse the outline tree to find the node's context.
