I have always read that passage like Zigur. Galadriel is leaving and Treebeard is staying and only if the world is remade will they meet again. Now it is possible that if the world were remade Numenr might be to though that might be regarded as a failed experiment and not part of the original plan and let alone. To extrapolate a divine plan for a specific individual in a specific place from a reference to a different place in an exchange between two other chaacters neither of whom is Eru. is just far too much of a leap for me.
