Forgive me if this is infeasible since I don’t know the architecture well enough, but what about using the MMU’s privileged position to watch for a specific peek or poke or both pattern and only then expose addresses?  Assuming that is doable, you could even have alternate patterns that would expose the MMU at different addresses so that it was run time selectable.
