CanJS as controller of controls from another framework?

I'm building a single-page app using controls from another framework, because I need the rich interactive controls.  I'm using Dojo to build the prototype right now although I could imagine switching to Sencha or similar because I really dislike the rest of Dojo.  Anyway, I've already built an adapter from that framework to CanJS views, ie. a View control which renders a mustache template that stays up to date as the underlying data changes.  That's simple enough but not sufficient because I can't constantly re-render entire areas, I need to do incremental updates that can't be expressed in a Mustache template.

Now I'd like to build a controller that affects the properties of multiple framework controls [ie not DOM nodes, but stuff hanging off them.]  For example, if I instantiate a "Menu" control (comprising Menu, sub-Menu, MenuItem, etc controls), then I'd like to have a CanJS model (control?) driving the options for that control.  End result is that I can say something like

  menu1.attr('submenu1').attr('label', 'Label 1');

  menu1.attr('submenu2').attr('disabled', true);

  menu1.addMenu({ ... submenu 3 definition ...});

  etc.

in CanJS code & my adapter will take care of calling the appropriate functions in the other framework to create,update,destroy various menu items.

The long-term goal is to use CanJS as the interface for a server that pushes updates to the client UI.  Rather than writing individual lines of code as above, I would be doing

   menu1.attr(new_menu_definition);

and relying on CanJS to parcel out a set of diffs which my adapter uses for updates.  Not like I'll be constantly changing UIs, but since each client's UI is driven by a set of permissions, this would give me a good interface builder + the ability to update the client on the fly when permissions change.  UI could also change based on data from other controls, ie. a checkbox here makes a menu item appear or disappear there.

Anyone seen or written something similar, where CanJS is used to drive external controls?  Thanks!
