I don't usually like the look of a cake with that much difference between the tiers. I would go with a 6 inch on top of the 9 inch with a thinner 12 inch tier on the bottom. Or if you want a 6 and 12 inch then put a dummy 9 inch tier in between them or a thinner 9 inch tier. I think you will like the look better.
