I have created a base-build Nuget package that includes all the doctypes, data types, templates, views, and controllers that I need to start building an Umbraco site.

I have installed this into a clean solution and for this particular website, I want to override one of the controllers e.g. in my package I have:

NavigationController : SurfaceController

And I want to create a new NavigationController like this:

NavigationController : BaseBuild.Controllers.NavigationController

The reason I want it to be the same name is so that I don't have to update any of the views that uses existing Actions on the base build NavigationController.

The problem is, when I boot Umbraco now I get the following error:

A route named 'umbraco-surface-Navigation' is already in the route collection. Route names must be unique.

So, is there a way I can completely override the base build NavigationController without changing the name, and without running into this error?
