Why do you want to implement it on the TypoScript level at all, if it 
simply should render everything? You could implement it in a later place.

How do you want it to interact with the caching mechanisms? Should it 
render before or after caching?

I think you could look into the tidy extension then. It offers both 
action before and after caching. So you should be able to learn from it.
