One of the problems with that idea is that WordPress doesn't currently have a simplistic way to identify a specific "page." Each resultant "page" is represented by an array elements in $wp->query_vars which are set by $wp->parse_request() when it attempts to match the current URL with the URL rewrite rules to determine those values. And $wp->query_vars can also contain elements that don't effect URL routing so you can't just URL encode that array to get a unique "page" identifier.  

Plus it's also possible to serve pages via the 'template_redirect' hook so you can't even depend on the results of $wp->parse_request().

So unless and until WordPress core were to standardize some method of specifying "pages" via a simple identifier (which I would be excited to see happen) then your idea is a nice one but not realistic.  FWIW.
