Should we simply have two wedding cakes?

Chinese Dumpling asked:


My fiance and I have different diets. I eat lots of vegetables and grilled fish and chicken while he loves sweets and cake. He is insisting on having a traditional wedding cake made with sugar and frosting while I want the low calorie variety make with splenda and egg whites and decorated with fresh fruit. He says that mine won’t taste the same and it is our wedding so we should do things the traditional way. Is he right and should I just give in? Would two small very different cakes look weird?
