Can node reference be altered to include views pages?
You could use a separate viewfield for the related views, and theme it so that the nodereferences and viewfields appear in the same list.

You could also use a link and use a custom widget if you don't wanna type the full path every time.

On a couple of sites I ended up never (or very rarely) using a view's page display. Instead I attached the view to a node, and always referred to the view via its node. This was because my advert banner system was based on nodereferences. It's not the most extensible approach, but it worked for those sites.
