What you're describing sounds like an edge case and goes against the design & development methodologies used in today's websites. Rarely are we building things with static content, and we're leveraging the power of AJAX to minimize the number of times a browser must refresh the entire window to load new content.

Current trends aside, from a pragmatic perspective, I would anticipate something like this increasing development costs (labor & money) between 10-50%, and would likely have a very low ROI.
