Wedding Cookie?

So, I'm in one of my favorite coffee shops working on a take-home exam and eating a black-and-white cookie (aka moon cookies) when I thought to myself:  I love these.  I wonder where the coffee shop gets them or if they make them?  I wonder if they could make a lot... like for a wedding? Naw, you can't have black-and-whites instead of a cake... or could you?

Upon further thought I decided that they would make a great alternative to a wedding cake.

Reasons:

1. They are super yummy!

2. They are made in a serving, so no cake-cutting fees

3. They have a cake texture, so are like cake

4. They should cost a lot less than a wedding cake (I'm only assuming, this is an unsupported statement)

5. They can be arranged in nice ways (see picture bellow)

Thoughts?  Have a come up with a new trend, or am I completely out there?
