Ok, I was thinking about that you mean somthing like this.
This isn't possible. Or let's say you mix up some parts.

The macro which you suggest is just a page template. This template
you are useing in a view. If this macro is also used in another view, 
it has in this usecase nothing to do with the other view. There is 
no relation, if you register a page template as a macro and a second 
time as a view, between the macro and the view.

Perhaps I don't understand this correctly. Can you post the ZCML
directive, then I see what you mean?
