That sounds interesting and I’d gladly see some more code samples of such architecture (the menu building code and how you actually pass title into the template).
Although putting view-oriented code into the router sounds weird to me, it may make sense to break out of the MVC bounds in more complicated projects. I remember coding (in Rails) a multi-module application with complicated menu structure that changed during navigation and I was struggling so hard to find a fitting place in the MVC to place that damn menu building code
