A more realistic scenario is that, in many years to come, Apple will phase out both of these product lines and introduce something new that takes the best of both worlds. But for now, I believe the iPad needs to stop trying to be something that its not and focus on giving users truly what they need - if that means a more advanced Finder-like 'Files' app, then do so in a typically iPad way, not through hidden menus, gestures, and multiple shortcuts/actions that lead to the same outcome in varying ways.
