I sometimes wrap really slow op amp loops around cap multipliers, but even with lead-lag compensation, it doesn't work that well. It's probably better to use a separate regulator after the cap multiplier if you really need a constant voltage. I typically don't use the supplies for voltage references when I can help it, so it's just a matter of the available output swing being slightly load dependent.
