Yes, as others have said, you can apply another coat of Natty's. It's just a carnauba over the AW which is a polymer.
I just applied AW over FK's Pink Wax and although I love the look, I understand what you are talking about. It took some of the glow, shimmer and depth of PW and made it a bit more reflective. Just the difference between a full polymer and something with carnauba in it to me.
The PW provided a bit of a mute on the finish which was fine because of the lovely glow and then the AW brought out more reflection. A nice combination of both to me.
The Natty's is wetter than the PW so you are likely seeing more of a difference than I see.
I reckon it's just up to you to decide which you like best but before you do, give the AW a day or so to cure and/or possibly do a few layers of it 24 hours apart.
