Hi Bojan

If your working with controllers in visual studio, rather than just in views; you can switch ModelsBuilder settings in the web.config to 'AppData' mode: (instead of PureLive)

<add key="Umbraco.ModelsBuilder.Enable" value="true" />
<add key="Umbraco.ModelsBuilder.ModelsMode" value="AppData" />

Now when you generate your models, you will find in the AppData folder a 'Models folder'

with generated c# classes representing each document type:

Include this Models folder in your visual studio project, and you can begin to use the strongly built models inside your controllers:

Each model has a contructor that takes an IPublishedContent so you could create a hijacked controller like so...

public class DocTypeAliasController : RenderMvcController 
      {
         public override ActionResult Index(RenderModel model)   
         {
var viewModel = new MyGeneratedDocTypeModel(model.Content);
        return CurrentTemplate(viewmodel);  
         }
    }

but in reality you'd probably created your own custom model that inherits from the generated model to add further custom properties that you would populate in your hijacked controller...
