I like your idea! It is very cute and simple. It reminds me when I was going through the Rabbits USA magazine an aritcle in there was of a wedding where the brides dutch rabbit was the maid of honor - She sat in a little stroller up there with them and one of the brides maids was the "designated bun keeper" or something like that haha.
Imagine having all your buns up there at the alter with you? hahaa
