Yeah, makes sense. Contenture already offers some enhancements for paying users as well. They're not as advanced as you propose but they go in the right direction.
Your idea is very good but I guess it needs one or two years to become a product or service, by then Contenture will have evolved into something similar I guess.
As far as I understand something similar already exists, at least twice. I only remember the whereabouts of one of those. It's a service launched recently by the people from Clicky Analytics. It's called Contenture.
