Minecraft Birthday Cake Candle

Hello it happens I have an idea for birthday cake. If you rename a candle into a number (for example 5, 10, 20... ) and then place it onto a cake, candle will have a texture of a given number. I think this would make a cool Easter egg and good for Realms when players celebrate birthdays. Unfortunately I wasnt able to make textures but candles in the shape of numbers can be found easily.
